GitLab

Some compile-time hacks in place to use MemLib, a dynamic area based
malloc replacement which shrinks its heap when possible. All builds
have these switched off at the moment. Seemed to work with just Browse,
though there would be problems with message blocks stored in dynamic
areas because of the Wimp's '&3800000' check - however, it failed when
HTMLLib was made to use it, too. Don't know why yet.

ItemInfo.[c/h] source added, with Res file additions for testbed Browse
and Phoenix.

Small fetch windows now work properly regardless of toolbar settings
in the Choices.

Reload now reloads all images too, rather than only reloading them for
as long as the main page was being fetched.

Added a simple 'Find' facility.

Realised that event handlers in eventlib are called in reverse order
of registration, so the miscellaneous event handler is now registered
first rather than last.

Multiuser code added (most only active if SINGLE_USER is undefined). As
part of this, hotlist code now knows about read-only items (done for the
Customer-style 'Resources' file, but works generally anyway).
handle_add_hotlist doesn't try to save the hotlist itself anymore (the
hotlist_add function does all that through hotlist_modified anyway).

Customer build Choices and Controls updated slightly (e.g. ClaimHelp
off, hotlist to save on quit only).

Customer build now uses Phoenix-style buttons. Sprites files which
worked at the time (but will probably be out of date now) and included
most of the original Customer-style sprites are in
'Utils.Icons.Customer'.

Choices, Messages and Res files for all builds now stripped down to only
single user items or single plus multiuser for Customer build and testbed
build. Before, all contained a few multiuser bits in at least the Choices
file if not more.

Grammatical error ("Fetching frames contents" (sic.)) corrected in
default message, Toolbars.c, and all of the Messages files.

Customer build brought back to a servicable level (including
implementation of the Find dialogue box with animation and fixing
up authorisation and 'Stop' state in the tristate). Quite a few
missing #ifndef REMOTE_HOTLIST bits from hotlist code added...

Customer build will not use <Choices$Write> or Boot:Choices for any
file finding now. UseProxy defaults to 'yes', MaxImages to 2. Res
file includes Proxy Address setting (save_save_choices() now writes
the ProxyAddress line).

The '3F6C0' abort fixed; reformat_left_margin didn't cope with a NULL cell pointer. This only happened if the image library tried to deal with an image in a table cell which wasn't properly dealt with by the table systems yet, for whatever reason. Rare, but persistent once it started happening because it depended on the value of the FIQ vector!

Put function header comments in SaveFile.c, at last.

Messages files now read version 2.01, 23 Feb 1998.

WindowManager 3.98. Sets URI handler environment variables for
http, ftp and gopher.

Fixed 'doesn't reformat for unsized images' bug - only happens when the
deferred reformatter is enabled, hadn't remembered to check this in my
debug build where this is turned off. Oops.

Caret position in forms could get left behind despite attempts to rectify
this in v1.31 - now fixed (and faster, fortunately).

Hourglass + percentage displayed for History and Image History when
loading - it can take a while for very big histories, though in
practice you only see the visit history loading (has to do a lot
more work, and is thus quite a bit slower than the image history).

POST forms worked when targetted to frames, but were broken when
not targetted! (Forms data inherited from one browser to the same
browser; ended up freeing the flex block...). Fixed.

Now support 303 response code (redirect to GET). Treated as 301, i.e.
not support if STRICT_PARSER is defined, otherwise drops through to
the 302 handling code.

Pointer shouldn't get stuck in odd shapes when going to a new page now;
it gets reset to a standard shape every time the null handler that
checks the position is called, though (whether or not the handler thinks
the pointer is over a different token, if that token is NULL, it sets
the standard shape). A possible work around would be for a browser to
remember the pointer shape too; that's for the future, though.

Early stage table formatting functions could blow themselves apart if
tables_count_table decided there were no rows, columns or both. A
net table size of zero cells is now dealt with; slow, partial table
fetches in multiple windows with image loading turned on will now
*hopefully* be stable, where v1.31 would have bombed out repeatedly.

A nested frameset within one document will now inherit the border
width (frame spacing) and border colour of its parent. This is done
by copying the maxlen and indent fields of the parent token over
the child, and note it's done in the browser (fetch_preprocess_token),
not HTMLLib.

Border colour on a FRAMESET now used, with the first colour on any
FRAME within it overriding, as in NN 4 and MSIE 4.

<LI> bullets really do stick to the text next to them now (I'd done
that in an experimental piece of code and forgotten to merge it back
before the last check-in).

Browse$HotlistURL/URIFile and Browse$HomeURL/URIFile now work from
_TaskName in the Messages file, and are thus of the generic form
<App>$HotlistURL etc. - Docs.Notes and Docs.User updated appropriately.

Event 0x11d00 through to 0x11d7f will make the browser look up Controls
file entries 'JumpTo00' through to 'JumpTo7f' and read a URL from them.
This will be fetched in the ancestor window of the source of the event,
or a new window if such an ancestor can't be found [for Daytona demo].

NB: Nasty frames-related crash at http://www.teledanmark.dk/menu/start.htm
is *not* fixed in this source. NOBR is not supported.

Check for WindowManager 3.97 and ensure Unicode$Path is set in all !Run[D] files, don't set the Alias$@PrintType_FF4 variable, and updated

Customer build ROM obey file variants. Various other changes to
the Run files for new module versions, updated paths to support
new positions of choices, hotlist and histories (see later), etc.

!Sprites[22] files hold small !app icons for some variants, and
an ic_browse sprite. Some variants now have a Sprites and Sprites22
file instead of just Sprites, with the former containing various
mode 12 or 15 specific sprites.

Text files dragged to the URL writable are treated as ANT URL files. This
relies on URLBarWrit (Toolbars.h) being a unique ID, which it should be,
but beware of the Hotlist and Choices numberspaces...

INPUT TYPE=BUTTON supported. Form items without a FORM tag are now shown
(as MSIE 4, but not NN 4).

'*', '-', '@', '_' and '.' are not escaped when submitting forms now. The
Web interface to the IMDb now works.

INPUT TYPE=HIDDEN items will not affect the line height anymore - so
http://www.hotmail.com/ now has correctly aligned writable icons, for
example. Similarly, TAG_FORM and TAG_FORM_END items could push up
line height and don't anymore.

HRs with a specified pixel width will now influence the size of a table
cell (they didn't before).

BRs now checked by tagno field when the browser needs to know something
was an actual BR tag rather than just a line break signal, and by the
style bit entry when only the indication of a line break is required.

Table widths of 0 or 0% are ignored.

Trace.c updated to report height and background fields in a table_stream.

fm_putsl() writes a terminator into the string; the Forms.c routines were
calling this for displaying INPUT TYPE=PASSWORD fields using the FE_PassCode
literal string (a line of stars). This write into a read only data area
would make the debugger fault the access. A local char array is now used
instead, to get round this (note the use of var[]=literal rather than
var[sizeof(literal)]; strcpy(var, literal) due to some weird compiler bug
that copies the wrong thing into 'var' under some (undefined...)
circumstances).

Text areas don't scroll back to the top line when clicked in anymore;
single line writables don't scroll back to the left either. When
reentering a text area from 'above', the caret appears at the top line
rather than 'somewhere further down'...

ARROWS_MOVE_OUT compile time option at the top of Forms.c defines whether
you must press Tab/Shift+Tab to move between writable fields in forms or
if up/down will drop out of them, though if keyboard control is on this
is enforced (or you get trapped inside the form!).

urlutils_filetype_from_url now uses MimeMap module.

If fetcher is told a page is text, it'll check for a filename extension and
may choose to use this instead (e.g. it may find it's HTML instead). This
is to try and get around duff servers... (e.g. http://www.batalarms.co.uk/).

Save dialogues shouldn't flicker when options that don't change the
filetype are selected (before, the draggable sprite was always reset for
each selection). Noticed the erroneous setting of a static variable in
SaveFile.c by a call to this by SaveObject.c, and so added a flag to
savefile_set_filetype to deal with this - would have been possible to get
the wrong filetype sent to applications or at best the wrong filetype
sprite in the dialogue without that.

The caret shouldn't jump out of a form back to the URL writable if the page
reformats now.

Table background colours now supported (as in the colour you see in the
border space if the cellspacing is large enough; this is as in MSIE, not
as in Navigator). Drawfile output routines updated accordingly.

Corrected erroneous use of wimpt_dx() / wimpt_dy() in a couple of places
in Images.c, which meant that (say) 1x1 images didn't work correctly in
medium resolution display modes.

Now have support for save as text (component ID and event 0x12) and save
as Draw (component ID and event 0x13) buttons. Dubious conditions for
greying and ungreying the print, save source and view source buttons and
menu options sorted out as part of implementing the same for the two new
buttons; added greying out of their associated menu items in passing.

Turned kerning on in draw file objects (does mean a rather heinous
increase in file size, but this is the only way to ensure the draw file
matches the visible page).

Comments before functions in SaveDraw.c are now complete and up to date.

Image and visit histories now generate a crude hash number to speed up
searching for items. It does give a speed increase, though it's a
disappointingly small one.

Issue of left/right margins and cellpaddings sorted out. Now have
redraw_left/right_margin for finding out the basic gap you must leave.
redraw_left/right_gap then gives any extra indentation for LI, BLOCKQUOTE
or whatever. The last two can be subtracted from the display width to
get an available page width for any section of text. Note that
redraw_left_gap replaces redraw_margin. The redraw_start_x function
uses the above to work out where a line's left hand edge should be,
taking account of left/right/centre alignment. HRs have been fixed now
(they were quite broken in v1.30, I think) based on this new model and
the behaviour of MSIE/NN 4.

Fixed width of cells with no contents - cell padding values wouldn't
have worked properly as the reformatter returns 0 rather than the left
hand margin size if given no stream.

Removed FM_Absolute flags for Font_Paint (spotted by DBrown) - sets bit
2, which is reserved...?

IMG width and height in % terms now works correctly; a % of available
width (after margins and indents) or height on the main page or for
a table cell, if the image lies in one. Because of the chicken-and-egg
problem with the latter, the cell must specify a width and/or height
for things to work properly. If this is not done, you'll usually end
up with a 1:1 scaled image (as in Navigator 4, rather than ending up
with no image or even no cell (!), as in MSIE 4).

HEIGHT attribute on a TABLE tag is supported, but only in a crude
fashion; the extra height (if there is any) is distributed over the
rows in a linear fashion. This is probably all you have to do in
practice, but I haven't checked. To maintain a notion of min/max
height as well as width would of course require a great deal more
work...

If using client pull to reload a page with a fragment ('...#name')
specified, then the reload wouldn't work on the same page; it'd just
jump to the fragment position. This won't happen if b->reloading is
set now (so works in conjunction with client pull on the same page
forcing a non-cached fetch). Similarly, if POSTing to such a URL,
a fetch will proceed (both these fixes done originally for
http://jupiter.beseen.com/chat/rooms/g/1678/).

browser_inherit split to browser_inherit and browser_inherit_post_data;
the code for the latter didn't clear any post_data in the child before
copying from the parent either, and could cause flex errors (now fixed).

Res file for Ursula ('Desktop' Browse) build tweaked - bits in the
font choices dialogue renamed, and button bar rearranged to hold the
new Save As Draw button. Other builds have had Save As Draw and
Save As Text buttons added, or not, depending upon availability of
suitable sprites, required UI simplicity, etc.

Now have:

  Browse$ChoicesFile
  Browse$ControlsFile
  Browse$ChoicesSave
  Browse$ControlsSave

(the last two are new) for loading and saving of the Choices or Controls
files. If unset, <App$Dir>.Choices or <App$Dir>.Controls will be set.
E.g., you could set Browse$ChoicesFile to be:

  <App$Dir>.Choices,Choices:WWW.(app).Choices

for loading and

  <Choices$Write>.WWW.(app).Choices

for saving. (The browser never saves Controls at the moment, so the
relevant variable above isn't effectively implemented, but could be
in future). Similarly, to support asymetric loading/saving of the Hotlist,
there are HotlistSave, HistorySave and ImageHistorySave entries in Choices
to complement HotlistPath, HistoryPath and ImageHistoryPath (which are used
for loading). save_save_choices will create directories as needed to obtain
the given path (and has also been fixed in various areas that hadn't been
tested out until now; e.g. zero termination of the AppName$ChoicesFile
variable expansion...). !Run[D] files updated appropriately.

Table widthing code rewritten. Slower, but a lot better on the whole.
Still has some problems - still needs a final 'make sure nothing is
below minimum width' scan, which it should be possible to do without.
No time to fix this at present!

The reformatter will now 'glue together' an LI token followed by any
non-LI token; so a bullet point followed by an item should not be able to
have a line break inserted after the bullet because of very tight width
constraints (it could before - yuk...).

'about:' brings up a page about the browser and any Plug-Ins, as with
Navigator (for example).

URI files support titles, as per spec. version 8. Saving a current
location to the Hotlist will thus give a sensible title now (unless
you're in a frame, so there's no title to get...). Of course, v1.00
files without a title still work.

Note that NOBR is *not* supported in this build and this combined with
the new table widther may cause problems on some sites (e.g. Microsoft's
home page!).

Not all resources are up to date in this check-in, and documentation both within source and stuff in 'Docs' is out of date or missing - I was very pushed for time on this one... Hopefully will do another 'tidy up' check-in before close on Friday; until then, beware of anything other than the Ursula (Desktop browser) build. Anyway...

Export As Draw done. As part of this, FONT SIZE and SUP / SUB adjustment
of font size is done in fm_token_font_info rather than fm_find_token_font.

Bullets and switches are plotted as indirected sprite items, rather than
indirected text + sprite items - this relied on being in a redraw loop to
pick the sprites up from the local pool (failed during printing).

URI files now have a LF line ending rather than CR... '*' recognised
as an empty field when loading via. RAM transfer now (only worked for
loading from disc before).

Gave placeholder bounding boxes 4 OS units more minimum extra gap
vertically and reduced horizontal addition to this value * 1.5, rather
than * 2 (see reformat_get_placeholder_size).

Background image tiling starts at ymax - h + 4, rather than ymax, so
there isn't the bottom line of pixels from the top tile always present
at the top of the window. The '+4' is for caution's sake.

Can now save a frame's HTML source, that of its parent or its ancestor,
and the same for the URI pointing to those documents - see Menus.h for
the relevant component IDs that should lead to the SaveFile dialogue.

Have hopefully fixed timeout = 0 values (i.e. 'forever') on things
like LinkTo; before, image fetches could override the state (so you'd
only ever see brief flickers of a given URL as the pointer went over
a link).

Save File dialogue will remember the state of option or radio buttons
for a given parent component origin and restore that state when the
dialogue is next opened from the same place (stops turning on saving
as a URL file also turning on 'save background images' for Draw file
export, etc.).

Use of a META tag to reload the *same* page now sets the 'reloading'
flag in the browser so that it doesn't go through a proxy - otherwise
pages which are meant to update periodically through client pull
don't work, as they keep coming out of the cache.

Can now handle images specifying just a width or height in the HTML
(other dimension is scaled accordingly, but note that the placeholder
size must still be 'dumb' until the image data comes in). An image
will now override an image history size entry for the same entry
with a different size.

Note that the 'Docs' documentation (possibly contrary to previous log messages) still hasn't been updated with the new SaveFile stuff, and function header comments have yet to be written for

SaveFile.c.

Fixed urlutils_pathname_to_url - OS_GSTrans doesn't like the same
input buffer as output buffer (fairly obvious, but I was living in
the hope of not having to duplicate the input path string).

Image history will not cache scrap file images anymore. Browser's
image handling library won't cross reference them either.

When dragging a single item from the hotlist to a Filer window, the
code now checks Ctrl - if held down, a URL file is written, else a
URI file. The state of any option buttons or radios in the last
Save File dialogue that was opened is no longer relevant...!

history_save_as_html could write out broken files when titles
for items in the History were not present. Fixed.

Hourglass switched on for hotlist and history saving as HTML;
hotlist_save_entries no longer closes the output file on error
(it should be done by the caller, since the caller is responsible
for opening the file and passing the FILE * pointer to
hotlist_save_entries).

There are a few known significant problems with this code but it's being checked in so the Choices can be worked on. Note that Res files etc. are not up to date across all builds. Progress is as follows...

Bug report prompted me to do this - now ignore <p> tags straight after
<li> tags, so '<ul><li><p>Some text' works as the author (or automatic
generator, more commonly) intended.

A <p> tag before a table will be acted upon now (it was ignored before).
Something like <li><p><table...> will give a line break and paragraph
space after the <li> despite the changes mentioned above, as in other browsers.
Both browsers differ from Navigator, where the table appears alongside
the <li> tag.

Multiple BR tags work as in MSIE / Navigator (they don't collapse to
zero height anymore).

For the above, line height (and so, <br><br> or <p> spacing) is now
calculated inside reformat_text_line_height, and is used with either
a token to get the text height at a given size (e.g. for general line
spacing or multiple BR tags) or NULL for normal size text (e.g. for
P spacing, though this value is in practice later scaled by 7/8ths in
reformat_check_height). Note this behaviour is exhibited by MSIE 4;
v3 gave two BRs the same spacing as one P (i.e. not font size
dependent).

Save dialogues can have an option button or couple of radios to
switch between various formats (e.g. URI or URL, sprite or original
format). See 'Docs.Notes' for more. The back-end to this is now
implemented (i.e. at the moment, save as URI or URL, save as original
image format). Note that when saving background images, a leafname
based on the original fetch URL is now offered rather than a generic
'Background'.

Internal URL scheme changed to be all lower case, so relativisation
through URL_Fetcher still makes sense... :-/

Holding down 'shift' when clicking on stop reverses the interpretation
of the Controls file 'StopWebServe' entry.

Fixed row / column count for exporting tables as text; fixed a few
bits and pieces of internal URL scheme stuff which got broken when
HTMLLib started using URL_Fetcher's relativisation.

Message_PlugIn_Busy. Plug-in code more robust when given invalid
browser instance handles by the plug-in.

Line spacing is now calculated on the basis of the normal style base serif
font, with all other fonts being forced into that line height. This does
mean that an unusually tall (say) sans serif font may get clipped. It
appears to be the only way to get around wildly different baseline
depths returned from the font metrics - you can't work out line spacing
based on each different font style; the line spacing will vary.

Table heighting (as opposed to widthing...) improved considerably; rowspan
can no longer cause very tall cells in odd places. Having trouble getting
rid of the single pixel breaks between vertically adjacent cells, though
I've not tried too hard. Widthing, though, seems fairly badly broken at
present... :-/

Set/clear of page_is_text flag made more robust (it looked as though there
was the potential for this to get stuck in a set state, though I've never
see the front-end behave in a manner which indicates this is the case).
The reformatter will now decrease leading if this flag is set (plain text
pages look daft with a line spacing that is OK for 'rich' text pages).
No reformatting is done if the page width changes by dragging on the
resize icon, though toggle size / full screen will still reformat even
if the contents are only text (browser needs to sort out various width
flags at this point).

Cut down on excessive redrawing when reformatting due to a change in
window dimensions is not done. If display_width hasn't changed, then no
redraw is needed. If this causes redraw problems, then whatever is
changing display_width needs investigating. It shouldn't be kludged
(basically) by forcing a redraw instead of a reformat.

TT/PRE/etc. text can now have a non-100% aspect ratio. 80-90% looks
best (ArcWeb, for example, uses 86%). New option 'TTAspect' in
the Choices files.

Debug builds link to a non-debug Unicode library now; stops stderr
being dumped to the bottom left of the screen if you've not redirected
it in the Run file.

RISC OS 3.1 seems to need more initial WimpSlot than later OS versions.
The 64 deep nested table set gives a 'No stack for trap handler' error
(which it really means in this case!) without 800K, even though 3.71
is happy with just 640K. So, the !Run file checks if Boot$OSVersion
is exactly 300, 310 or 311, and sets the WimpSlot accordingly.

!Run[D] files now require latest fetcher module versions (URL 0.21,
File 0.31, HTTP 0.58).

Image history - sizes of images are remembered for future reference (if the sizes aren't specified in the HTML, they can be looked for in the image history instead to minimise reformatting requirements). Choices file options ImageHistoryPath, ImageExpiryAge, ImageMaxSize and

SaveImageHistory added to support this (all have a direct analogy to
the global History items of the same name after removing 'Image').

Text area items are now the correct height for the number of rows
specified in the HTML, don't scroll a line too early, and have the
caret placed at the start of the text when moved into from above
or at the end when moved into from below (rather than always at
the end, which was behaviour inherited from single line writables,
where this is desirable). The top of the text area is aligned to
the top of any line of text on the same line, with the text area
dropping below the text, rather than the bottom of the area matching
the text baseline and extending upwards.

Filename extensions for download files are only stripped if an
attempt to convert to a RISC OS filetype through the Mime Mapper module
does not return an error or Data (0xffd) filetype. '.cgi' is a special
case which is always stripped.

Altered heading styles - all are bold, none are italic, H3 is as big
as H2 was, H2 is a little larger, and others scale down to H6 being
the size as normal text (but, as I say, bold).

Sorted out tables and forms. We can just look for tagno=TAG_FORM, and
get rid of the wobbly form_flag; also discarded the redundant
reprocess_table flag in fetch_preprocess_token. Two separate forms
in consecutive table cells (for example) which used to fail - they
were submitted as one single form - will now work correctly.

Fixed nasty bug in FontManage.c where font size 7 would intermittently
fail. The stupid font sizes that it could ask the Font Manager for may
be responsible for the occasional Font Manager crashes that have been
noticed. Array for font sizes was declared as [Limits_FontSizes], but
indices 1 to Limits_FontSizes are actually used - so needed a '+ 1'
in the declaration... :-/

Replaced the case insensitive string comparison functions in Utils.c
with more efficient versions by S.Brodie.

MAXLENGTH specifier in INPUT tags is now supported. If unspecified or
specifically zero, the browser overrides and allows any length.

All hotlist_find_match calls wrapped in '#ifndef REMOTE_HOTLIST' compile time option, for Customer builds.

Cross referencing of images when the background colour is different - should
not do it for backgrounds, for e.g. alpha transparent PNGs would then fail.
This was implemented, but it turns out it affects *all* cross referencing!
Fixed for just background images.

As described in Docs.TagNames, the tag name "ahodgkin_127beta2" associated
with this checkin applies to everything *except* Choices.c. v1.27 beta 2
was build with the Choices file tagged "ahodgkin_127beta". The confusion
arises because Choices.c got independently updated and checked back in
before I checked in the v1.27 beta 2 changes myself.

This is an intermediate check-in to allow work on Choices for the new table options and History choices as detailed below. Res files are not up to date except where indicated and there are several known bugs that will be fixed before the 'final' v1.27 is created. Any work on resources should only be done for the testbed !Browse.

Client side image maps implemented. There is code to draw highlighted
borders in CSIM.c, but this is not wired in yet; other than that,
the implementation is functionally complete. As part of this, centralised
the fetching of a targetted URL taking into account user request of a
new view and full screen mode, in fetchpage_fetch_targetted. The forms
library now uses this too, so form buttons respond to both adjust-clicks
and TARGET attributes.

Fixed APPLET handling where '.class' isn't present in the CODE attribute.

Paragraphs squashed at the top of cells/pages - browser would insert white
space before.

Now append a ' ' to the end of History menu items to prevent the Wimp
thinking the end of entries represents a keyboard shortcut (e.g. 'Home').

Netscape's handling of 'meta http-equiv="refresh"' is to start counting
when the fetch has completed and everything else has died down. The browser
will now not start counting until the animation handler is deregistered
(so formatting is complete) to show similar behaviour (note that this
checks the main handler, not the 'idle but returning to first frame'
drift handler).

URLs from requests for fetches by Plug-Ins are now relativised.

Page width change tolerance prior to reformat upped from 16 to 32 OS
units. Hoping to provoke a loosely connected bug with this change!

TableOuter, TableInner and SeeFetches choices added to all Choices
files, with appropriate loading and saving code in Main.c and Save.c.
AuthorFTP and AuthorFSh messages added for FTP authentication, and
dialogue handling code (the component in FetchHTML.c) updated to
recognise an FTP fetch and alter the dialogue presentation
appropriately.

All Messages file version numbers taken up to 1.27 (20 Nov 1997).

Following a UseNet suggestion, Ctrl+Toggle Size will increase the window
size to fill the screen vertically only; horizontal size/positioning is
not changed.

Shift+Tab in the URL writable will cycle through alternative fetcher
protocols (from both the Controls file and checking the fetcher modules
are actually present).

Hotlist doesn't require '://' in URLs when loading HTML, just ':/' - so
'file:/' URLs now will be reloaded correctly.

History system rewritten completely. GHistSize and VHistSize options
removed, and replaced by MaxSize and ExpiryAge. Now have global history
menus with most recently visited items at the top, and local history
menus which reflect the path that forward/back buttons would take.
Browsers are robust to background expiry of the History though this is
not implemented - date expiry and size checks are carried out on
history_record only. This does mean that with two windows open one could
have the history expired underneath it whilst another fetched, though;
the code handles this and update toolbars (greying items) as necessary.
It is possible to have the history limits so tight that even one entry
will not fit and again the code copes with this, though values read
from Choices are limit checked to ensure rather more useful results!

Implemented 'Save' button in save dialogues. Remembers pathnames and just
replaces the leaf now (hard coded exceptions for <Wimp$Scrap>... and
<Wimp$ScrapDir>...) - it did before, but only if you'd typed the path
in. Not many people did, given that you couldn't press Return or click on
a Save button to use that path...

In a similar vein, files of type Data or DOS will be checked for a '/xxx'
type extension and the MimeMap module will be used to find a more meaningful
filetype. If this can be handled, the file is loaded. This only works for
files dragged to the browser - the behaviour with inline data in web pages
will depend on the File module, and similarly, if File doesn't spot what is
going on and claims that the object is data, the browser will just open a
save dialogue for it.

!RunD files taken up to 3072K WimpSlot.

Hotlist's saved HTML page title wasn't internationalised - is now. This
opened up a significant can of worms; on file write error, the file would
never be closed, and if a caller of the save or load functions passed
in a filename held in the global Messages lookup buffer then subsequent
lookups in the callees would corrupt that filename. All sorted out now.

Local (not very useful) or global (useful) histories can be saved as HTML,
which opens up the possibility of sending your history to the hotlist
by saving to it. Local and global histories can also be emptied, though
this is probably not a feature that current release Desktop browsers need.
Inheritance of local history and certain UI features is now done more or
less for all cases where one browser window spawns another, too.

Vertical alignment on images is rather less ropey than it was (e.g.
ALIGN=TOP stands half a chance of working) but is still far from perfect.
This was part of fixing a nasty little bug in Redraw.c's setting of
an image position via. image_set_token_image_position, which was making
(amongst possibly many other things) client side image maps fail.
Image update where images had large borders was affected by a similar
problem too (more cans with more worms...).

Fixed image background filler functions; two problems. When cross
referenced images were replaced by base images in a browser because the
original owner was closing down, the original owner browser would stay
registered with ImageLib. Fixed; secondly, when images were deleted from
the image array causing those above to be renumbered, images registered
with ImageLib did not have their numbers updated (this was the one that
lead to the visible drop out of background images with PNGs on the Acorn
Internet home page when there were two views of the page and the first
was closed). This is now also sorted out.

Removed 'The Onion' link from some Hotlist files. Time showed that the site wasn't entirely Family Friendly (TM)... Removed Shift Control (it's gone offline now), and corrected the Telegraph URL from ...the-telegraph...

to just ...telegraph...

StrongHelp manual generator now tries to work out the number of lines in
the table on the root page more intelligently.

Plug-in support extended to handle Shockwave. Quite a lot of underlying
work for this, including a pseudo cache system for temporary files.

Bug in redraw routines: they plotted background images within table
cells, when nothing should have been drawn. Oops. When background images
in cells are properly supported, this can get sorted out.

Tweaked vertical plot position of HRs (up to 4 OS units too high before due
to rounding).

Various Res file bits and pieces, Ursula build taken up to v1.26 beta
for release on the Browser site. *Note* not all resources are up to date!
This will be done after AW97.

Added support for background alpha PNGs.
Passed support_object flag through to HTMLLib.

fetch_get_raw_data will notice if up->fetching is zero and return a 'finished' status rather than trying to continue reading data for the fetch. Fetches should never fall through that far but at least it will cope if they do.

3D table borders are now supported. 2D borders are used if the
inter-cell spacing is too small to fit the borders in (display resolution
dependent) - the external table border is 2D if the internal borders are,
else 3D. For cellspacing of 0, internal table borders must plot over the
outer edge of pixels inside the cell; for all greater spacings, the
borders take up all or part of the gap between them. The external border
will always fit around the outside of the cells, including the
cellspacing value in the gap between the outer cells and the border.

Anti-alias colour for placeholder ALT text was incorrect. Fixed.

I'd changed 'point' to 'points' in some of the Font Choices dialogues;
now changed back to 'point'.

The routine to find out how large an otherwise unsized object or image
placeholder based on its ALT text has been centralised in Reformat.c,
so that the image and object routines can both access it without
code duplication (this means non-image objects will now have the correct
size if they contain ALT text, rather than assuming a standard default
size as before). ALT text in images that were also objects was never
plotted either, though the placeholder size would have been correct.
This has been fixed.

Main.c, so the last log was incorrect; Navigate menu items wouldn't have
been greyed out. Probably a(nother?) CVS update screw up on my part; now
fixed. This sort of thing is happening far too often...

Font manager would crash in system font or if a font face was not found
in the previous release - that hacky business of returning weird font
handles when system font is to be used instead ensured a rather less than
valid array reference on behalf of fm_claim_basic_typefaces.

Added in a few more calls to the 'check the button bar' routines, to
ensure that things like Stop are greyed/ungreyed when needed.

Cellpadding code could lead to rmarg overlapping lmarg, or the sum
being greater than dwidth, or something like that (!) in the reformatter.
Anyway the results were unpleasant; this has been sorted out by range
checking right and left margins w.r.t. display width in the relevant
section of the code.

People who specify 'td width = 2000' in tables expecting to get something
sensible now do, though I was half inclined to leave it alone... I can
only assume that they don't know about % specification or it didn't
work in their browser at authorship time, and the huge width served as
an attempt to get the table to fill the available window width. Anyway,
the table reformatter spots when the maximum width a cell requires is
less than half of what it asks for, and ignores the width specifier if
this is the case.

Now handles PARAM tags. Sorted out Plug-In bug that was related to Java setting a 0 by 0 graphics window before calling Wimp_Poll (fixed in Java).

Implemented queue for Plug-Ins so multiple broadcasts aren't sent for
several Objects in one data chunk.

Added Docs directory with some documentation in it. More things to keep
checking for stylistic consistency, horray ;-)

Corrected !Run[D] for Ursula build to need AcornURI but not TaskModule
(URI handler needed for !Mail to pick up mailto: links).

Added display_height field to browser_data, analogous to display_width,
to cope with % sized objects by width and height (see how HRs are
handled in Redraw.c for an example of how it was always fairly easy
with width, but not height until this addition). Though you do have
to reload to get a new size; reformat isn't enough. Must see to this
some time...

Fixed bug where basic typefaces were claimed *before* the Choices file
had been read. For unusual Choices settings, this could create some
'interesting' problems now and again. This was part of narrower scope
work in the Choices code to allow font changing without leaking font
handles (now done; fm_shutdown only ditches fonts, it keeps internal
structures - must then call  fm_lose_fonts for all browsers to get the
bitfields up to date, then rewrite the typeface definitions and reclaim
basic fonts). Noticed that fm_claim_basic_typefaces would claim multiple
instances of the same font if there were several cases of the same font
mapped to different typeface styles - fixed.

Implemented PlugInControl settings, but not SupportObject (fully).

Places where ModeChange should be called in image_fill_background marked, but commented out (because of problems with flex moving when redirected to a sprite).

A few more tags added to Trace.

More reformatter code bugs fixed; this one regarding width of items. Any kerned string was overestimated (causing redraw bugs and caret position problems in forms, apart from other minor bits elsewhere) and the default size of a writable icon wasn't especially clever.

Crude Plug-In support; just about manages Java, but can't fetch on
behalf of Plug-In (for example). Had to change the default file access
URL construction to be 'file:/' instead of 'file://', or local file
fetches that reference Java applets won't work. This is in its very
early stages, and is being checked in mostly so that various Choices
issues can be worked on.

Added MimeMap module support. OBJECT routines now use this to determine if the item is an inline image, and if so pass it to the image routines.

At present, support relies on a (correct) content type.

Text items with no VALUE specified in the HTML were not cleared on
hitting a Reset button as the text field of the token is NULL; fixed.
SELECT lists with no default selection item were not being changed
on hitting a Reset button; fixed. In radio groups with no default
selection specified, no item will be selected. This goes against
the HTML 2 spec but allows broken Navigator-esque forms behaviour.
In consequence, radios can be deselected by clicking on the same
one twice. I'd fixed the flickering experienced when doing this
recently, but that, now, is irrelevant, since the state of a radio
must always change.

Reformatter's new 'find width of a SELECT field' didn't account for
the width of <none> and <many> items, and now does (particularly
important for broken items with no OPTION contents).

Under certain circumstances, illegally named targets would open in the
ancestor rather than a new window - a deliberate decision in the code,
but now reversed due to a test suite failure; they'll open in a new
window instead.

Altered the left hand indent handling for lists so that headings and
body text follow the Navigator 48 pixel indent and the bullet point
items drop to the left of the left hand margin, rather than sitting
on the margin with the text indented to the right.

Tightened up the hotlist_load_directory checking of URLs, so that
only those with '://' in - i.e. look fully specified - are accepted.
HTML files are loaded into a new directory now.

Items without a descriptive title in hotlist_new_url will have the URL
substituted in instead. White space before and after descriptions and
after URLs is stripped. Directories with zero length names or null
strings (after white space is stripped) will still be created, with a
generic name (see Messages, token 'HotlistUntitled').

StrongHelp generator on it. Revealed a spurious toolbox_hide_object call
that would always fault and never do anything, and a few heinous uses
of show_error which have all been removed.

When dragging hotlist items, directories will now be highlighted whenever
the item would be added to them, rather than just over the sprite. In
practice this only changes if the item is open and has contents...

Drag box selections had broken in the hotlist; fixed (uninitialised
variable in hotlist_select_box). Adjust-drags now close the window on
completion. Minor problem with Shift+Drag (copy) reversing order of items
sorted out. Added hotlist_add_html_file and implemented loading of HTML.
DO NOT add broken HTML files, this has not been coded for and URLs of the
form http:///this/that (no host name) will hang the machine (bug in the
cookie code of the HTTP module up to at least version 0.39).

Made SELECT list items only as wide as the widest entry actually appears
(using fm_get_string_width), rather than as wide as the widest character
BBox in the font multiplied by the string length of the longest entry.

Updated !Run[D] files to require HTTP 0.39, FTP 0.12 and File 0.23.

Choices and Controls files are now loaded into malloc space (use chf and cof to address them). Previously only in Main.c, task_dir is now globally visible.

Choices updated to allow 16ths of a point in the font size specification
and the System font face has been removed - it isn't used. The use of
serif and sans serif fonts has been rationalised across builds (e.g. Desktop
builds use what they say, but the Customer build uses Homerton as the
default body (serif, so to speak) font as it matches the box's look and
feel better).

Font loading altered a bit to work properly! Font library defines some
standard startup fonts without using Choices, which Choices can then
override.

Now working on source merged with Kevin Bracey's internationalisation support. UNIFONT is undefined in the Make File for now. All Res and

Choices files updated appropriately.

Having sorted out the old Choices and Messages to form Choices, Controls
and Messages, this build has had the same cleaning up done internally.
This includes greater consistency in naming schemes and the removal of
the inconsitent choices items - e.g. Choices file entries saying 'delay
images' and 'plain backgrounds' where internally all the flags say 'show
images' and 'show backgrounds'. ChoiceDefs.h and CtrlDefs.h added to
clarify the meaning of some fields, though usage of these is not 100%
in the source (there are cases where parameters are passed through to
functions as ints, and those functions still check these against hard
coded values rather than the #define stuff).

Fetcher status return bits (connected, sent request, etc.) now reflected
in status bar. Progress during fetchs to files are reported by %, where
the size of the object is known. Exceeding 100% drops back to a byte
counter, in case the estimated size was wrong. The progress counter
may be updated after specific delays, rather than 'as often as possible',
to reduce flicker (as requested by D.Brown some time ago).

I've done a small rewrite of the fetch prioritisation scheme in FetchPage.c;
how well this performs in general use across different processor speeds
remains to be tested, but certainly it has some advantages. For each small
fetch window before the rewrite, a 4cs tight loop was entered - this gave a
noticable and substantial drain to the Desktop performance if more than one
was opened. Now, several can be up at once with little hit. The actual file
fetch is on half the priority it was before, with all others taken back
just a bit - e.g. from 20cs per poll to 15cs per poll for flat out
reformatting. You don't seem to lose much time on the format in practice,
and the Desktop feels quite a bit lighter at the same time. There's the
potential for smoother frameset loading in this scheme, too.

When Shift+Clicking on a link meant you still fetched inside the main
browser window, several fetches could occur in a frameset - one per frame.
However, now that you can only do this by clicking on a link that leads to
non-displayable data - or by turning off the small fetch windows by
setting UseSmall to 'no' in Choices - a bug where fetchpage_preprocessed
would stop such fetches as new ones were started was revealed.
The API to frames_abort_fetching has now been extended to include a
'stop file spooling too' flag, allowing a fix to be made by having
fetchpage_preprocess's calls not set this (and it doesn't check the
savelink flag is unset before proceeding, since frames_abort_fetching
does that implicitly now).

Had left the RAM transfer buffer at 16 bytes (from testing) accidentally...
Oops. Upped it to 4K. In addition, when loading data by RAM transfer,
the browser didn't notice if a RAMFetch bounced during the transfer. It
would be treated as a 'first' RAMFetch bounce, basically, and try to go to
file transfer - oops. Fixed.

Image deletion routines rewritten; nasty animated GIF bug now gone
(it kept trying to update the cross-referenced image in the browser that
no longer existed, and I've no idea how animated GIFs ever managed to *not*
blow up if a cross referencing browser was shut down; and I've tested
this...). There are now as many image structures as there are total images
in the visible browsers, and no more; cross referenced images in the
to-be-deleted browser have their ownership moved to the cross
referencer before the cross referencee is wiped, with any required fetches
being transferred with them.

Reformatter sped up a bit by getting rid of strlen on the main text field
of tokens in all places bar one, where it is called extremely rarely. This
means direct app-to-app transfer of, say, a 359K text file to the browser
won't run like a drain as it tries to do strlen on a 359K string over and
over again! Most of the time the performance benefits won't really be
noticable, but on the above text file, formatting time went down from
290 seconds before the change to just under 7 seconds, a 41 fold speed
increase or thereabouts (SA110 228MHz).

MakeFile changed to force function name compilation on for debug builds
(-fn in the DD...FLAGS); useful for certain functions such as
register_null_handler, which can now output the name of the function
being registered.

...Which helped show up some nasties in the animation handler and animation
drift handler registration/deregistration process, which have been fixed
(callers of fetchpage_release_nulls were unaware that the drift handler
could be installed, and fragments of old code checking choices.anim_drift
had a value other than 1 or 0 were still hanging around - bit tricky for
a single bit item).

Added support for VALIGN in table cells. Spotted a bug or two in the
'what token is the pointer over' routines as a result, and fixed them - the
worst was in browser_line_at_y, which checked the y coordinate was below
the given one [the mouse], but didn't check the line height to see if the
given y coordinate was *within* the line, rather than just above it. Never
used to matter pre-tables, but a definite concern once multiple line
arrays can exist on one page.

As warned in the last log, pretty much all event codes and component IDs have now changed along with many of the names, to provide a consistent name and numberspace for events and components. This also minimises number clashes (e.g. as was, the Save File origin when opened from a

Hotlist menu with an already-used component ID). To get full details on
this, please carefully read through TBEvents.h.

Res files, Sprites files and Messages files have been updated again both
due to the above, and routine additions (e.g. message support for a few
Hotlist bits and pieces). !Run[D] files updated for FTP 0.11 and
HTTP 0.36.

In the Makefile, the Customer objects list was missing Save - must have
moved something when I should've copied it, when adding in SaveFile or
SaveObject in all probability. Now fixed. Couple of other bits and bobs
fixed in the build environment (e.g. stuff saying !Argo instead of
!Customer). Oh, and I've altered the MakeFile copy options again to the
best compromise I can come up with. Newer is turned on for everything
except !Run[D] and !RunImage, since both of those change between debug
builds - otherwise if you'd built debug and non-debug versions, it was
not possible to switch between them - one version would have the newer
timestamp and thus never get overwritten.

The default hotlist has had a few items added - that'll be about the end
of it, I think; there's more than enough stuff in there now.

Saving of the hotlist from the document menu and of URI files,
directories and selections from the hotlist menu tree is now implemented
- this new save system rocks... Oh, and you can save all images and
backgrounds as sprites.

Saving of items with Shift+Click to other applications directly now
works, and is robust. Unique Scrap filenames are used, with data load
bounces (e.g. if some pra - er, person quits the app they're sending
to) working correctly - that is, give an error, keep the file, rename
it to something safe, and open the directory it lies in. As opposed
to normal app-to-app bounces, where the scrap file is deleted (see
PRM 3-254). This means you can now look at README files in FTP
sites, say, without using a disc intermediate. Or you can send pictures
straight to ChangeFSI, fetch HTML links into editors, and so-on, and
so-on - it's all very funky. Known problems include the ambiguous
'invalid component ID' instead of 'file open' for *normal* (straight to
disc) shift+click saves, and I think I'll introduce a unique name
guarantee of some sort to stop 'file open' in the first place. Odd
that the really tricky part (app-to-app) should be least likely to
suffer from this!

Only the Browse resources are currently valid.

Added Utils.Icons - has a few archives inside containing the resources
(well, some of them) used to build various UI sprites for various builds.
Archived because these are unlikely to change much, and putting them on
CVS was a move to, well, archive the stuff...

SaveDBox objects vanquished and requirements in !Run[D] files removed. The
data save code fits much more neatly in amongst the data load protocol
stuff now (with the slight exception of having to split the SaveObject
source into SaveObject and SaveFile - the former handles multiple persistent
dialogues for Shift+Click on links and the like, the latter handles 'one at
a time' transient dialogues for save source and similar). Export Link is now
supported, too, and writes a 'proper' version URI file. You'll find that
double-clicking on old URI files will work as the URI handler picks them up,
whilst new version ones don't; however, dragging onto the browser will only
work with new version files. Note that support for saving and loading URL
files (ANT suite stuff) is present too, so old URI files can be typed as URL
files if you want to keep them working without modification - the URI
handler itself will hopefully support the defined URI file format soon;
double-clicking on old URI files will stop working at that point. Note
there are *lots* of changes in every Res file to support all this. This may
all seem a bit pointless to some, but the changes do in fact make it very
easy to add new save dialogues all over the place. Certainly much easier
than with the previous system, anyway. In fact, post script, image
'save as sprite' took about half an hour, which I hope proves the worth
of the new system.

Merged in newer hotlist code with support for drag cancelling with Escape
(all relevant Res files appropriately updated) and cancelling scrolling
when you've reached the window scroll limit. Had to move some of the
Wimp message handling stuff to the central Protocols source, as clashes
were occuring, and also the hotlist routines were using independent saving
code - a lot of duplicated effort. This was fair enough as at the time the
Hotlist code was written, the Save code couldn't be used in the way it is
now.

New Save Source and Print buttons on the toolbar of some builds.

Phoenix Sprites file made more efficient - the Acorn base section has been
split from the animated upper region. Browse build has a new grey fade
sprite at the back, which is less grainy than the previous one and only
uses 16 colours (with a 16 greyscale palette).

Not really a bug, bug the routine to start an image fetch for INPUT
TYPE=IMAGE forms items only did so if the src field (or equivalent, for
this tag type) was non-NULL. In fact, you should always call image_new_image
and let that handle the rest, otherwise other sections of the code will fail
as they try to obtain an image number for a given HStream and get -1 back.
This problem only generally manifested itself when loading an HTML file to
the browser straight from an application, as many src fields become NULL
when the relativisation routines find nothing to relativise to...

Authentication got broken somewhere along the line - this has been fixed
(in HTMLLib and the browser).

Ctrl+Click on a cross referenced image updates *all* copies, not just the
one with the image data attached.

Next big step: Rip up TBEvents.h and rebuild that whole approach somewhat.
To all those working on the code, my apologies but this means all Res files
will receive a very large number of alterations and there will be extensive
code changes too (mostly naming convention stuff), in more or less all
source files. I am endeavouring to ensure that the new numberspace
convention does not clash with the work being done by Kevin on
internationalisation.

Open URL implementation more or less complete, though may undergo UI
revision at a later date to allow named frames to be targetted. Hope to use
the ideas in this code as the foundation for other general dialogues.

In token stream dump for TRACE builds, table head items were not indented
as far as they should have been - this is fixed; and manual toolbar redraw
routines have been removed. They never worked, were commented out, and
would never be used in that form anyway.

DragBox source added, but it isn't at all complete and won't work - this is
an 'in spare time' thing. We need custom drag boxes constrained to windows
for the hotlist, and unconstrained for frame border resizing... Hey ho.

Ancestor window extents match visible areas if there are frames (no more
scrolling framesets...!). Frame resizing works whilst new documents fetch
without pulling the extent down now. However, frame horizontal extents
never shrink until a reload which is nasty, and this is all due for a
rewrite. Frames border redrawing routine moved out of Redraw.c and into
Frames.c. Bug regarding the mouse rectangle and frame border widths
(rectangle was too large, so you could squash the edges) for edge-drag
frame resizes fixed.

Window width change reformat tolerance fixed; you could creep the window
width down or up forever without any reformat, and centred objects would
move but not be redrawn (thereby giving rise to subsequent redraw errors).

Filetype on objects saved through Shift+Click correct. Save Source dialogue
recognises if that source is plain text, rather than assuming HTML. A
browser that fetches a file remembers the old store size it had before the
save, so even though the data is now ditched, it reports the same amount of
data fetched afterwards (looked awful when this could, for example,
suddenly say '0' after a file save). Progress indicator is now fully aware
of one or many file saves inside a frameset and reports the number of
saves, a colon, and the cumulative saved data count, instead of reporting
the sum total of fetched data in all frames, including non-file save stuff
(note that for just 1 save, '1:' is not shown as a special case for the
most common condition). A bug related to this, where you could in fact only
do one fetch per frame*set*, has been corrected (only one fetch allowed per
frame still, this is unlikely to ever change).

Hotlist support added (D.Brown's source), with various bits of integration
and modification still in progress there. Note additions to the Messages
files. On the subject of Messages, the whole mucky business about what
goes in Messages or Choices (and a few bugs where lookup_choice was used
instead of lookup_token or vice versa) has been sorted out. Messages
contains, more or less, just that. Choices contains user configurable
stuff which generally can't mess things up too badly. A new file, Controls,
is a Messages file holding the non-user configurable choices, which can
generally make things go badly wrong if misused. A lot of these are tied
to the Res file. StrongED users can get these to automatically fold out
the various sections (EMail me for details). Sorry, but at the time of
writing, Zap doesn't do folding... =8*P

Two bugs with images. Asking for images to be shown in browser B when
browser A uses the same ones and was loaded first didn't work correctly,
and now does (a bit weird - browser A does the fetch and browser B does the
display...). Second one occurred when the background image was also used on
the page as a foreground image. This has been fixed by flagging background
images in the image_info structure, and checking this before cross
referencing. This bit also allowed the image_restart_fetches API to be
extended, so that just background or foreground images may be fetched if
they weren't already and the user asked the browser to show them. Before,
the whole lot had to be fetched together (so turning on 'display
backgrounds' will now kick off an image fetch if required, you don't
need to reload the page anymore).

Makefile copy options tweaked to be 'newer' (so if you're testing with some
temporary Choices file or something, it won't write over it at the end of
every export), and REMOTE_HOTLIST flag added for Customer builds - means
the Hotlist.c functions aren't needed; the old, hotlist-by-file method is
used. Added support for Customer build (see later), though there were very
few additions needed in practice.

Table printing fixed - in many ways it wasn't broken, it was image printing
causing the oddities ever since the global image pool was introduced (this
is, again, fixed). The 'reformat to fit page' option didn't work as coded
any more; tables store cell addresses in the HStreams, so you can't then do
a background reformat in a different browser. Hence, it now has to reformat
to the page width, print, then put the page back again, all in the actual
displayed browser. This doesn't feel as slow in use as it perhaps should,
considering what is going on... Note that a line of a defined fraction (see
Print.h) of page height will now split over page boundaries, so tall images
or tall tables don't cause problems now (aside from the obvious problem of
having the line split over a page at all!). There was a bug in the routine
to print from a given start point until 'n' pages had been filled, in that
it always filled 'n + 1' - now fixed. Finally, as part of the printing
tweaks, a new dialogue exists - PrintStyle - with a similarly named source
file added to deal with it.

Global history auto save / load done, but only to the Choices file path -
the whole browser is still strictly single user at present, with all the
extra work for a multiuser Customer environment yet to be done. This has
shown up a global history corruption problem which I haven't fixed yet.

Rationalising TBEvents.h - things are migrating out of it, and into more
appropriate sources (e.g. definitions relating to the Open URL dialogue are
going into OpenURL.h, etc.). Event codes were at one stage deliberately
diverged in numberspace from the component IDs of typical gadgets raising
the events, to avoid anyone getting confused and thinking the IDs and event
codes must match. However, this is in fact unlikely and it is much easier
to remember the fewer numbers that result from tying the two together where
possible. This has resulted in changes to event codes raised in the
following objects of all Res files: Authorise, Find, OpenURL, and
PrintStyle.

And finally - !Run[D] files for all variants updated to require the latest
toolbox and fetcher modules. All Res files updated for hotlists etc. and
sprites files updated appropriately. All Messages, Choices and Controls
files brought in sync., and an Customer build has been added (based on the
Desktop build binary with different resources).

That's all for now...

Added right-align support.

Limits.h, and ensured consistent comment styling throughout all sources.
Fetch.c/h split to Fetch, FetchHTML and URLveneer. URLstat.c/h produced to
cope with this. OpenURL and Find sources created from bits in the Windows
source file that shouldn't have been there... These will get filled out
shortly. Note that a few functions in Fetch are due to be renamed and moved;
probably to Tokenutils.

Quite a few general source changes throughout many files to sort out swapped toolbars. There will be more work on this shortly. svcprint.c has been modified to allow it to output to a file in PipeFS, so TML-less machines can still use the standard browser debug routines (albeit in a less than elegant fashion). Comments in that source file give more details. Plus a few more bug fixes.

Fixed problems with unsourced images in tables and a couple of other bugs here and there - nothing earth shattering... Just wanted to keep the CVS source up to date.
