Icon bar Shift F12 behaviour changed back to RISC OS 3.7 style, which made far more sense than the bizarre "simplified" scheme some Ursula spec review cooked up.

Version 4.94. Tagged as 'Wimp-4_94'

Added automatic translation of spaces to hard spaces in writeable icons that forbid the former but allow the latter. This effectively allows spaces in filenames.

Version 4.87. Tagged as 'Wimp-4_87'

Detail:
  * Bugfix: the contents of the pollword returned in the poll block by
    a PollWordNonZero event, where the pollword was flagged as high
    priority, was rotated by 8 bits due to a internal top-bit-set
    workaround. This no longer happens. (This was causing OmniClient never
    to complete initialisation on my machine.)
  * Extended the alternate resolution icon scheme for RAM/ROM sprites and
    toolsprites to be multi-pass, enabling the use of extra sprite sets for
    weird modes (most notably EX0 EY0 ones). After '23' or '0' suffixes
    (the latter still only applies to toolsprites), the suffix for the
    equivalent polychromatic resolution is tried. After rectangular
    suffixes, the next larger squarer suffix is tried. After '11', '22' is
    tried. Failing all of these, a match is attempted with no suffix.
  * The command window is now scaled and centred to match the current screen
    mode - up to a maximum size of 1280 x 1024 OS units.
  * Fixed the *WimpVisualFlags help strings (again).
  * Fixed 'task2' debugging to know about the structure of the SVC stack on
    32-bit machines.
  * Added support for generation of GPA files.

  Tested on Tungsten.

Version 4.84. Tagged as 'Wimp-4_84'

Detail:
  RISC OS 4 changes:
  * Font blending for desktop font (based on NC code, but now configurable)
  * 3-D window/menu/iconbar borders
  * Textured menu backgrounds
  * Loss of rubout box in unfilled text+sprite icons
  * *WimpVisualFlags controls various aspects of cosmetic changes above
  * Iconise button "slot" glyph slightly shorter (but only adopted in the RO400
    Resource directory)
  * Command window has front-window flag set
  * Byte at +39 of the window block has gained two new flag bits:
      bit 2 set => this window must never be given a 3D border
      bit 3 set => this window must always be given a 3D border
      (note that ResEd erroneously created windows with both bits set,
      this case is treated as though both bits were clear)
  * Another two colour specifiers on the end of C validation string command
    for icons controls the foreground and background colours to be used when
    the icon is selected
  * Pointer shape is correctly reprogrammed by the creation of icon
    underneath it
  * Full stops in writable icons are treated the same as spaces from the
    point of view of cursor navigation
  * spritesize routine returns a size of 0 if the sprite didn't exist
    (probably fixes some rendering problems)
  * Adjust-click on back icon brings window to front
  My changes:
  * DeleteRight turned on
  * Icon bar title background is set to default in all resource sets (avoids
    translation table recalc)
  * Error box title now cream across all resource sets
  * RISC OS 4 changes made 32-bit compatible / high addresses safe
  * Undocumented FullIconClipping option disabled
  * Command help made consistent for internationalised and non-
    internationalised builds
  * WimpVisualFlags defaults made sensible
  * Menu side width affected by ThreeD option at *run* time not assemble time
  * Right-clicking on menus with writable items no longer data aborts
  * Auto-opened menus are now at RHS of current icon (matches RISC OS 3.1)
  * Colour menus were knackered unless menu tiling was enabled
  * Fixed a bug whereby adding messages to a task that wanted all messages
    actually caused it to lose all other messages. The RISC OS 4 fix for
    this didn't work
  * Fixed bug introduced in version 4.76: tasks that wanted no messages got
    all of them
  * Autoscrolling is updated every 8 cs rather than every 12 cs
  * Added menu texture to pre-RISC OS 4 sprites files

Version 4.78. Tagged as 'Wimp-4_78'

Detail:
  All pointers passed to the Wimp (mode selectors, menus, sprite areas,
  palettes, pollwords, validation strings, message lists, routines etc etc)
  in any of its APIs can now be anywhere within the 32-bit address range.
  In general, whenever "<= 0" was accepted as a null condition, the value
  must now be either 0 or -1. It should also be tolerant of system memory
  areas (supervisor stack and RMA) being in the top half of memory.
  Also:
  * Default next slot now a build option - Ursula builds (eg Tungsten) use
    1024K instead of 640K
  * Ursula builds no longer have a build variant in the help string
  * Autosenses ROM location
  * CR-LFs in *Configure messages replaced with LF-CRs
  * Added Iyonix resources (currently based on Morris4)
  * Morris4 sprites files have gained file_lxa, small_lxa, file_unf,
    small_unf and lo!help sprites
  * Ursula sprites files have gained lo!help sprites
  * *WimpSlot can take memory sizes in megabytes or gigabytes
Admin:
  Tested on a "traditional" memory-mapped Tungsten.

Version 4.76. Tagged as 'Wimp-4_76'

Detail:
  * The pointer passed to Wimp_CommandWindow can now be top-bit-set.
  * Bugfix to Wimp_CommandWindow: if the current task was uninitialised,
    or initialised as a non-multitasking task, then although entering the
    CommandWindow would restore escape condition generation to the way it
    was before entering the desktop, exiting the CommandWindow did not
    reset escape condition generation to the default desktop state (which is
    for escape condition generation to be disabled).
  * Escape condition generation is disabled for the duration of SWI
    Wimp_ReportError (instead of setting the default escape key for the
    duration). The previous state is restored on exit.
  * Added a minimal environment for the service call
    Service_ErrorButtonPressed, so that claimants can call OS_Exit without
    leaving the global Wimp error box in an undefined state.
  * In the Wimp_Poll loop, if there are no events to deliver to any tasks
    (not even null events), then rather than sitting in a SVC mode loop,
    the Wimp now triggers transient callbacks. This is particularly
    important in order not to halt all activity in the Internet stack.
    The option LeaveOS can be set to make the Wimp use the as-yet
    unimplemented SWI OS_LeaveOS for this purpose; this is currently unset
    for all builds.
  * By (persistent) request, reinstated the old iconbar popping code,
    though it is currently a build switch that is turned off for all builds.
Admin:
  Tested on a Risc PC.

Version 4.69. Tagged as 'Wimp-4_69'

  Updated to build using objasm instead of aasm.
  Sources changed to be objasm-compatible.
Admin:
  Requires Library 0.71 or later.
  Requires BuildSys 3.06 or later.
  Requires Env 0.65 or later.

Version 4.64. Tagged as 'Wimp-4_64'

Detail:
  * Added new functionality for menu trees: submenus can now be opened by
    clicking on their parent menu item. This is particularly aimed at
    touchscreen devices, and is configurable via the new *Configure keyword
    WimpClickSubmenu.
  * Change to the menu inactivity timeout behaviour after auto-opening of
    submenus (either by hovering over the parent menu item or by the new
    click-to-open functionality): although all hover operations are still
    ignored for this period, any click operations *will* now be obeyed.
  * Corrected numerous misleading comments in the menu handling code.
  * Added some suspiciously absent ALIGNs in the *Configure keyword handlers.
  * Uses new ASCII case-forcing macros so there are now fewer warnings
    printed during assembly (and it should run faster now too).
  * Added an AREA directive so that objasm's -ABS switch is no longer needed.
  * Standardised ErrMem token across all Messages files that use English.
Admin:
  Tested on a desktop machine.
  Requires HdrSrc 1.06.

Version 4.57. Tagged as 'Wimp-4_57'

Detail:
  Lots of little changes throughout a lot of source.
Admin:
  Appears to work - not stress tested with things like lots of tasks, big
  transfers, and all the other things that tend to go wrong.

Version 4.47. Tagged as 'Wimp-4_47'

(This stops system font character 128 being reprogrammed to a tick, and also
stops the desktop font being switched to WimpSymbol when character 128 is
encountered.)

Version 4.32. Tagged as 'Wimp-4_32'

(this was clashing with the Interlace module at one point during STB
development, and had the potential to trip us up again in the future).

No longer produces build errors if some resources are absent.

Corrected token in Japan messages file to use valid UTF-8 character.

Service call table now included by default.

Version 4.23. Tagged as 'Wimp-4_23'

Version 4.20. Tagged as 'Wimp-4_20'

Added options file for Ursula_RiscPC builds: similar to Ursula options file, but without UTF8 support (it's unlikely the rest of the modules will be updated sufficiently for this to be useful) and without the development cut-n-paste support. Also removed module postfix (we don't want "Ursula" appearing during a *Help Modules).

Retagged as bavison_Wimp-4_11.

Optimisation to new WimpSymbol substitution code: in icons containing fonts other than the desktop font, the substitution table is only calculated when a symbol character is encountered.

Embryonic cut-n-paste support introduced (currently in desktop builds only):
  * workspace is allocated and initialised;
  * extended Wimp_GetCaretPosition implemented;
  * pushfontstring adapted to allow insertion of arbitrary control sequences in
    font strings (to allow selected text to be plotted in inverted colours).
Inverted, unfilled text icons now work properly again in <256-colour modes.
Reworked NC error box code: see Doc.IconHigh.

Version 4.11. Tagged as 'Wimp-4_11'

Adapted assembly process so that the choice of Options file (previously based purely on the "System" variable) can be overridden by passing "OPTIONS=foo" as an argument to either MkRom, or to amu/amu_machine directly, or indirectly, by specifying it in the components file for a build. To accomplish this, it was necessary to switch from using aasm to objasm - hence the large number of source files affected in this commit.

Version 4.09. Tagged as 'Wimp-4_09'

UTF-8 support from previous version switched in; additional alphabet- conditional support added as follows:

* Correctly converts character index returned from Font_FindCaret into byte
  index into raw string.
* Left-arrow, right-arrow, delete-left and delete-right now act as far as
  the next character boundary, instead of to the next byte.
* Menu item text justification works again (it relies on overwriting spaces
  with hard space characters, which are two-byte characters in UTF-8).
* General key handling code has been rewritten. The Wimp now has three
  internal key input buffers - one each for taking keyboard-generated,
  task-generated, and function-key-generated strings. Each input buffer is
  processed in chunks of one character, rather than one byte; malformed
  UTF-8 characters are rejected, so tasks don't have to worry about them
  (simplifying their character-handling code). There is also a key output
  buffer, to ensure that (UTF-8) sequences of Key_Pressed events are not
  broken up.
* As a result of the above, multiple calls to Wimp_ProcessKey are now
  possible between calls to Wimp_Poll. Previously, this resulted in bytes
  getting jumbled up - making it useless for input of UTF-8 characters.
* Multi-byte characters are inserted into writeable icons in one go, so you
  don't see a brief flicker of the "malformed character" symbol while the
  initial bytes are being inserted.
* Multi-byte characters that don't entirely fit in a writeable icon buffer
  are not inserted at all.
* A new validation string command ("U") can limit the contents of a
  writeable by number of characters, instead of bytes. This will hide the
  character sizes from the user interface.
* Allowable characters (validation string command "A") now works on Unicode
  characters and character ranges.
* Various other minor bugs are fixed (Wimp_ProcessKey 13 can activate a
  writeable menu item, Shift-arrow keys are always consistent in firing off
  Key_Pressed events, etc.)
* Password icons supported: one symbol is displayed for each character
  (instead of for each byte); the display character (validation string
  command "D") can be any UTF-8 character; correctly displays the caret
  after set-caret-by-index calls, even though characters in the processed
  string are different width to those in the raw string, in password icons.

Other changes:
* The border around NC-style error boxes is resized when the error window
  is grown or shrunk.
* Messages, CmdHelp and Template files made consistent across resource
  directories, including support for all Ursula features.
* ShrinkableAreas turned back on in System=RCA builds.
* User interface features of desktop OS builds standardised.

Version 4.06. Tagged as 'Wimp-4_06'

Changed to use srccommit.
All conditionals on "Version" removed.

Version 4.01. Tagged as 'Wimp-4_01'

Made options files specify any text wanted after the module version number.
Auto-fronting iconbar now returns to previous position rather than back, so
it interacts with Shift+F12 better.
