      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.

      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.

      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.

      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.
