      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.

      Andrew Hodgkinson authored
      !Run[D] files updated for new fetchers and GopherFetcher; protocols list in Controls updated for Gopher. Debug builds now require 2760K rather than 2560K. Font$... variables set if not already, in anticipation of font
      
      Choices work.
      
      Additional bits in Choices section of Res file tidied and some name
      changes (e.g. Netscape -> Navigator(TM)). Frames support option added
      to Choices.
      
      Grouped 'support_frames' under the Fetch Controls section and added
      support_object in Global.h; appropriate entries placed in the Choices
      files, and are read at startup. At present, though, only the frames
      support flag is implemented.
      
      For some reason, Menu was the button to use on history popups if you
      wanted to show URLs instead of descriptions (or vice versa, depending
      on Choices settings). Now, Select and Menu will show the Choices
      defined setting, and Adjust will show the opposite.
      
      History menus are built backwards, so local histories have the most
      recently visited pages at the top. Global history has still no real
      order to it, but this may be arranged later.
      
      Customer name changed to Customer by request.
      
      Customer browser now gets its own resources (SYSTEM=Customer), but
      otherwise is unchanged, with the Ursula build now giving the
      'spinning acorn' with a Bookworm-style toolbar. This is used for the
      Desktop !Browse build.
      
      !Sprites[22] files updated to include GIF, JPEG and PNG sprites;
      !Run[D] files and !Boot files set appropriate File$Type_xxx variables.
      Sprites in all sprites files have been checked for unnecessary palettes,
      which have been removed where present.

      Tidied up Hotlist source a bit more, mostly so PSI can use the automatic · 26e079aa
      Andrew Hodgkinson authored
      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.

      Andrew Hodgkinson authored
      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!

      Created Protocols source file and moved a lot of message handling from... · f3e8124f
      Andrew Hodgkinson authored
      Created Protocols source file and moved a lot of message handling from handle_messages - the latter now serves as a high level distributor to lower level functions in Protocols. Incidentally, URL files (as used by the ANT suite) can be loaded by dragging to the browser in the same way as URI files - Not A Lot Of People Know That, etc.
      
      Merged new hotlist display type Res file to existing resources, added
      support for DataSave message so items can be dragged from the hotlist
      to a specific window (RAM transfer for URI and URL files; ScrapFile for
      HTML and Text but deleted afterwards and there are appropriate guards
      to stop Reload just saying 'not found'; images run through ScrapFile and
      there is no choice but to leave them there and do a conventional fetch).
      
      All !RunD files now give a WimpSlot of 2304K. Some small changes to
      the Argo and Ursula build Res files to make the menu trees more sensible.
      Controls files now take 'file:/' instead of 'file://' in Protocols
      section. Definitions at top of URLutils.c *not* altered, as then you
      end up with invalid URLs - so it will accept 'file:/', but always generate
      'file://'. This is because some browsers exports 'file:/'. Sigh.
      
      make_no_[..._]memory_error functions now return a _kernel_oserror * rather
      than void. It's always &erb returned, but it enables users to use a more
      elegant 'return make_no_memory_error(1);', say, rather than something
      like 'make_no_memory_error(1); return &erb;'. I obviously should've written
      it like that at the outset, but never mind. All callers have been
      appropriately updated.
      
      The urlutils_leafname_from_url function now replaces illegal characters
      (A7000 Welcome Guide p54...) in the leaf with legal alternatives.
      
      Internal URL scheme is now a bit cleaner, with everything properly defined
      in URLutils.h. All references to http:, file: and ftp:, with or without
      a following '//' use the definitions in here now.
      
      More tidying and some reorganising of Hotlist source. Auto-open delay is
      now a Choices item. Some dependencies on statics removed (e.g. the
      counting functions don't accumulate into the global item_number now).
      The redraw functions used Wimp_TextOp - oops, so this has been amended
      to use whatever is supported on your Wimp. This is now in a new function
      (utils_text_width()), which the History menu routines also use (there was
      a bug in the width routine there anyway, which is therefore fixed in
      passing). Several other routines used Wimp_TextOp directly too, and
      they have been altered to use the new function as well.
      
      In hotlist code, one of the larger changes is in the API to hotlist_draw_r()
      (formerly _hotlist_draw()) which now takes item widths and heights as
      parameters - discovering these is quite slow, so doing it every time the
      function calls itself recursively is a little less efficient than
      passing the values in from elsewhere. Note that underscore prefixed
      functions are being slowly renamed to _r suffixed functions, to match
      the convention established by Tony Cheal with is table routines. This
      makes it much more obvious when something is recursive, as the same
      naming convention is used in every browser source file.
      
      Finally, note that I intend to ditch SaveDBox and use an alternate window
      with manual control of the messaging in Protocols.c. This will allow
      various improvements which at present the SaveDBox operational methods
      preclude. I'm going to have to do at least an alternate Window object for
      the SaveDBox module to use soon in any case. Getting rid of SaveDBox will
      help reduce, if only slightly, demands on the RMA.

      Very long log entry alert - but hey, beats 'Bug fixed' (sorry, Richard) ;-) · 532155bd
      Andrew Hodgkinson authored
      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...
