      Got the deferred reformatter working properly. It doesn't do that 'OK, the page is fetched and reformatted, but just to annoy you, I'm going to wait 5 seconds and then suddenly reformat the whole thing again' trick anymore. The fetcher was calling the reformatter in a delayed form even when the reformatter was already running, so it would carry on past the reformat point or from below what had become and invalidated line, and some time later, get back to the delayed reformat. Now, reformatting is only delayed by the fetcher when the reformatter is not running. In practice this means body text reformats as it fetches, but large tables will show delayed reformatting - which was exactly the intended behaviour of the feature when it was originally thought of.
      
      fetch_token_data_address removed; it was only needed in two places,
      both of which already knew when to read tp->text and when to ignore
      it. Its functionality is duplicated in an 'if' involving reformat_istext,
      anyway.
      
      !Run[D] files taken back to requiring HTTP 0.33, since 0.36 introduces
      many weird and wonderful problems.
      
      Typo in Messages files, 'All current images (sic.) fetches finished' -
      'images' is now 'image'.
      
      Shift+Click saving - you could save to an application. No problem. But
      the equivalent (just clicking on a link that led to an unknown datatype
      and getting the save dialogue that way) didn't work. It does now.
      Another problem was saving to an application that didn't support the
      datatype - oops, the dialogue would close but the fetch would sit there
      waiting to be told where to save. It doesn't close now (as expected).
      
      NB, doing several simultaneous fetches to a text editor may have problems
      as the editors are too clever for their own good. Despite receiving
      DataLoad messages for <Wimp$Scrap> for files of different types, sizes
      and datestamps, the editors can decide it's still the same file and:
      
      Zap      - Hats off, it gets it right, almost. You do get warned 'Multiple
                 copies - one on disc is newer' as everything after the first
                 text loads, but they do load, and in separate windows.
      StrongED - Does not load the subsequent files, so the browser gives 'Data
                 transfer failed' errors and opens up Scrap. Turning off 'Don't
                 load same file twice' fixes it - each file is loaded in a new
                 window with no warnings. At least in the first case, you don't
                 lose data, since the files are kept in Scrap.
      Edit     - Each time it loads the file, it *replaces* the other one in
                 memory, using the same window for each. This is the worst
                 behaviour as it isn't configurable (well, I don't know of a way
                 to change it...) and results in data loss as successive texts
                 get trounced by the new data.
      
      I can't see how I can fix this in the browser as it's basically silly
      behaviour on behalf of the editors. Other applications which don't try
      to work out if it's a new file or not are fine!
      
      When conducting image fetches, proxying is allowed unless reloading.
      When conducting page fetches, proxying was never allowed - so web cache
      stuff would have been, er, interesting. It now sets X-NoProxy: in the
      request header when reloading, but otherwise this is not included.
      
      AnimSpeed is, at last, independent of browser poll speed. They used to
      be tied together. Guess how the animation code used to work ;-)
      
      'Can't handle this datatype' - deprecated now that save dialogues can be
      popped up. The 'can't save objects in full screen mode' error would never
      be shown due to a bug, anyway; this now replaces 'can't handle', which
      has been removed from all Messages files.
      
      RefoWait, RefoHang and RefoTime moved from Controls back to Choices.
      
      Trying to get rid of strlen in the reformatter - it can get very slow
      (e.g. strlen of 8K chunks of text, or if a 330K text file is transferred
      from a text editor straight to the browser, strlen of a 330K string...).
      There will be unfinished bits of code in the reformatter that may seem
      unnecessary - they've just not been plugged in yet (since they don't
      actually work). Don't remove them!

      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...

      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.

      (adding up to a greater whole), which include removal of the dastardly
      'invalid image number' errors that trace builds would raise from time to
      time. Frame highlights are now better controlled (releaseably so).
      Generally, this build represents the first genuinely promising version
      of the browser for quite some time, despite the known library problems
      with comment handling etc.
