Not all resources are up to date in this check-in, and documentation both within source and stuff in 'Docs' is out of date or missing - I was very pushed for time on this one...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.

Adjust-click on forwards/backwards buttons did not work in the intermediate
build, and now does.

Adjust-click on form submission buttons where the submit method is POST
will now work correctly, as the new view inherits the extradata block
of the old. Failure of this is signalled through
make_no_fetch_memory_error, code 16 (see updated Errors file in Docs).
Note the name change of extradata in this context; more details below.

The passing of forms POST data and extra headers for sending in an
HTTP request via. the URL module was all done through pointers into
flex blocks, and was therefore very unsafe. All relevant functions now
use pointers to pointers to the data.

To remove confusion on the umpteen uses of the word 'extradata', the field
in browser_data has been renamed to 'post_data'. The 'extradata' parameters
used within FetchPage.c were all disconnected from the extra header info /
form POST data stuff that extradata is usually associated with, and have
thus also been renamed, in this case to 'appnddata' (Append Data).

As well as X-NoProxy, the browser sends the 'proper' HTTP headers
Pragma:no-cache and Cache-Control:no-cache.

A redirection from a POST request was not handled correctly; despite
what HTTP specs say, you're supposed to use GET for the new URL. The
browser was, but when it chopped off the redundant header data in the
request didn't terminate it and left Content-Type in anyway...! Fixed.

Ctrl+Tab implemented - URL completion. Comes from the hotlist URLs,
hotlist titles, history hosts, paths, full URLs and lastly titles.
See code comments for more (history_find_match, hotlist_find_match).

TableSupport option added to Choices; it is read, can be set by the
front-end, but doesn't actually do anything else yet.

Reversed Choices' semantics on 'don't expire by...' for History. Added
'needs_redraw' flag to choices_get_contents so that, for example, if the
table border types change, browsers get redrawn.

Updated Res files in appropriate builds to hold various (similar) Choices
designs.

Choices related menus were flagged as Shared, but none of the dialogues
(including ColourDBox) were - potential future problems, though shouldn't
cause any leaks at present. This has been sorted out anyway.

Encoding function encoding_init no longer returns an error from
toolbox_create_object, so the Encoding menu and all those attached
to it do not have to be present (e.g. the Customer build).

SUB, SUP, STRIKE and U supported. U underlines the baseline of the body text
font, whilst STRIKE will go through roughly the middle of the lower case
chars even if the font is SUP or SUB. Note that Navigator appears to shift
the underline point for SUB and SUP; it may be necessary to copy this
behaviour, but testing on real sites must proceed before that. There could
also be a problem with the automatic lowering of font size, which Navigator
doesn't do, so any FONT SIZE = -n commands could make it too small. Again,
this needs testing on real sites.

'http://' is added to URLs with no protocol specified, unless they start with
'ftp.', in which case the new behaviour is to add 'ftp://'.

Choices code altered to do less error checking on components! They should be
able to be missing without raising errors. Referencing of the subwindow
array changed from *(subwindows + number) to subwindows[number].

Made trace_tag_name code look pretty...

reformat_useless_token now checks tagno is non-zero.

User Agent string setting now done through URL_GetURL, on a per-session
basis.

Ellipsis character removed from all Messages files, replaced with '...'.
There's little difference between the two in an outline font, and in System
font the latter looks much better. Smart quotes left in, as they look
better in all cases.

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.
