Version 4.96. Tagged as 'Wimp-4_96'

Detail:
	usergroup had identified a Hi bit set (32bit) issue with
	PollWords that existed in a hi bit set DA. There is evidence of
	previous work to avoid this, but a hi bit set pollword address
	could leave a V set condition floating around. Added CLRV to ensure it
	was cleared.

Version 4.95. Tagged as 'Wimp-4_95'

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'

Moved the Hdr:NdrDebug routines so that debug versions build.

No change to production binaries, so not tagged.

Detail:
  Now exports VersionNum to the BBE.
Admin:
  Tested in a Tungsten BBE build.

Retagged, since this won't affect any existing builds.

Details:
  s.Wimp03 : lines 502 to 505 moved 4 lines later
Admin:
  Tested in rom at Castle. fix believed benign at Tematic


Version 4.93. Tagged as 'Wimp-4_93'

* New options file for STB
* Changed some ADRs to ADRLs so that they reach for the options combination
  for STB

Version 4.92. Tagged as 'Wimp-4_92'

Variants pre-Ursula now build again.

Version 4.91. Tagged as 'Wimp-4_91'

Fixed an errant top-bit-set pointer problem with submenu pointers.
Removed startup sprites from Wimp sprite pool - now live in Desktop module.

Version 4.90. Tagged as 'Wimp-4_90'

Wimp_ReportError would loop indefinitely if the error string was zero length and the desktop font was an outline font.

Version 4.89. Not tagged

Wimp_GetPointerInfo should include shaded icons, in particular so that they
can now have interactive help. Included some information on RISC OS Select
APIs so that we can avoid clashes.

Version 4.89. Tagged as 'Wimp-4_89'

Version 4.88. Tagged as 'Wimp-4_88'

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:
  * All tasks have erroneously been flagged as receiving all messages since
    version 4.78. Correct behaviour is now restored, and the previous
    fix (to ignore Wimp_AddMessages calls for tasks that already wanted
    all messages) should be unaffected.
  * Check for "P"-validation icon creation under the pointer was broken
    in three ways, now works.
  * The optimisation of multiple Message_SlotSize calls is overenthusiastic,
    and can lead to some messages being lost if the slot size is changed
    (including as a side-effect of OS_ChangeDynamicArea) during
    high-priority pollword-nonzero handlers or message handlers for
    Message_SlotSize - in both situations, a message block that may have
    already been delivered to some tasks is still present at the head of
    the message list. Now, the optimisation always ignores the message at
    the head of the message list.

  Tested on Tungsten.

Version 4.86. Tagged as 'Wimp-4_86'

Resource tweaks: changed floppydisc label; corrected *WimpVisualFlags help to use present tense like all other help strings do.

Retagged as 'Wimp-4_85'

Detail:
  * Adjust clicking on menu items was leading to Message_MenusDeleted being
    broadcast, resulting in incorrect behaviour in many applications.
  * Sprite-only menu items (eg !Draw's line pattern submenu) now highlight
    correctly when tiled menus are configured.
  * Added Wimp_Extend 13, which works out the appropriate resolution suffix
    for a given sprite pathname - required since Sprites11 support needs
    an iterative approach. This supercedes Wimp_ReadSysInfo 2.
  * *IconSprites now tries prefixing the last element of its path argument
    with "<Wimp$IconTheme>".
Admin:
  Tested on Tungsten.

Version 4.85. Tagged as 'Wimp-4_85'

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.
Admin:
  Tested on Tungsten.

Version 4.84. Tagged as 'Wimp-4_84'

Detail:
  * Validation string commands to set the pointer shape were incorrectly
    interpreted if they contained commas to set the active point.
  * Holding down shift when clicking on the back icon will only move the
    window by one position within the window stack.
Admin:
  Tested on Tungsten.

Version 4.83. Tagged as 'Wimp-4_83'

A few bugfixes, and some muching around with WimpVisualFlags that I did ages ago but hasn't made it into a build yet.

Detail:
  * Deleting icon 0 in a window that had no windows would rotate the
    contents of word &00000010 by 16 bits. This had the effect of causing
    lazy task swapping to blow up with an "undefined instruction" error.
  * Setting the caret to a byte position beyond the end of an icon's text
    would (a) loop indefinitely if the alphabet is UTF-8, or (b) data abort
    for any other alphabet. This was due to the code trying to determine the
    number of characters in the string, and ignoring the terminator;
    skipcharR would never advance far enough to satisfy the loop in UTF-8,
    in other alphabets it would advance as far as necessary, leading to the
    later code to try to step a huge number of characters through the
    pushfontstring copy of the text, running off the top of the SVC stack
    (which is mapped out on Tungsten, previously it abutted the system heap,
    so no ill effects were observed).
  * Keyboard shortcuts are now correctly positoned when 3D menus are selected.
  * Corrected spelling of "dialogue" in *WimpVisualFlags help.
  * Changed *WimpVisualFlags so that no parameters gives RISC OS 3
    behaviour, and -All gives default RISC OS 4 behaviour. (Previously, font
    blending was enabled in both cases, unless explicitly disabled by an
    additional -NoFontBlending switch.) This required a sense change in the
    font blending switch: -FontBlending now enables font blending.
    -NoFontBlending is still accepted without error, but is ineffectual
    (since the no-options state upon which it acts already has font blending
    disabled).
  * Default setting is now as though *WimpVisualFlags -RemoveIconBoxes had
    been executed. (In practice, this will not be noticeably different from
    previous Tematic versions, see below.)
  * The state -RemoveIconBoxes switch was previously assumed always set -
    now, if it is not specified, you get the old RISC OS 3 behaviour back.
Admin:
  Tested on Tungsten.

Version 4.82. Tagged as 'Wimp-4_82'

Detail:
  * Removed Acorn/ACORN from keyboard shortcuts.
  * Added Red/RED/Green/GREEN/Blue/BLUE (and an attempt at German
    versions too) to keyboard shortcuts.
  * Capitalised the 'B' in -Fully3DIconBar to hint that it's necessary in
    the short form of the switch to *WimpVisualFlags.
Admin:
  Not tested.

Version 4.81. Tagged as 'Wimp-4_81'

Fix to Wimp_DeleteIcon stiffing the machine when trying to delete an icon which doesn't yet exist.Now fails gracefully.

Import of another set of awful icons in the Iyonix resources.
Tweak to the number of CLI parameters accepted by * commands.

Version 4.80. Tagged as 'Wimp-4_80'

The application space size returned from OS_ChangeEnvironment includes the &8000 below the application slot, and our Message_MemoryMoved handler wasn't taking account of this, hence the way module tasks randomly acquired 32K wimpslots in the Task Manager! Also updates appslotsize variable on task switches, to remove some false positives.

Version 4.79. Not tagged

Detail:
  * Message list pointers passed into Wimp_Initialises that didn't follow
    Wimp_StartTask used to be corrupted
  * Stack imbalance in ExitPoll if SWI Portable_Speed didn't preserve flags
  * 32-bit mode test speedups
  * Builds without RO4 option set
Admin:
  Tested on Tungsten and Risc PC.

Version 4.79. Tagged as 'Wimp-4_79'

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:
  * Default UpCall handler is installed when an application is paged out,
    so there is no danger of it being called by naughty people issuing
    UpCalls in the background.
  * AMBControl builds now sit on Service_MemoryMoved so that they can issue
    Message_SlotSize when the kernel has resized the application slot
    independently (eg because the memory was needed to grow a dynamic area,
    and nobody objected via Service_Memory or UpCall_MovingMemory).
  * Medusa-onwards builds no longer request Service_ValidateAddress, because
    we're not managing the free pool any more, and the code that was here
    only called an ineffectual SWI!
  * SafeChangeDynamic wasn't setting the CAO high enough to be free of big
    application slots; now it points it at itself.
  * The free pool wasn't being shrunk/grown enough on initfirsttask /
    closelast. It still can't do by more than 1GB without stiffing - bug in
    kernel?
  * Bugs in top-bit-safe changes fixed: dragbox resizing was broken, Escape
    state wasn't being restored for new tasks.
Admin:
  Tested on high-ROM/stack, 48M-appslot Tungsten.

Version 4.77. Tagged as 'Wimp-4_77'

Put back in a change to Service_Memory that I regressed while tracking down a bug. Retagged as 'Wimp-4_76'.

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

Version 4.74. Tagged as 'Wimp-4_74'

Detail:
  * Makefile change to allow install phase to work correctly with the
    shared makefiles.
  * Added some Japanese resources for the STB.
Admin:
  Builds and installs.

Version 4.73. Tagged as 'Wimp-4_73'

Detail:
  * Keyboard shortcuts in menus are now correctly aligned (and menus will
    be one pixel wider to compensate for the downwards rounding in SWI
    Font_ConverttoOS).
  * There is no longer any danger of menu titles being treated as though
    they contain a keyboard shortcut.
  * Dialogue boxes may now contain nested windows.
Admin:
  Tested on a Risc PC.

Version 4.72. Tagged as 'Wimp-4_72'

Detail:
  Auto scroll in Filer windows is now on to stop blank error boxes
  when you try "rubber band" selections.
Admin:
  Tested and works.

Version 4.71. Tagged as 'Wimp-4_71'

Detail:
  The titlebar and input focus colours for the window template for
  error boxes is now cream (12). This is more intuitive. Builds which
  do not have a title bar will not look any different.
Admin:
  Included the little utility which did the modification in Test/ResMod
  (as in Resources Modifier - but who cares). May be of use in future.

Version 4.70. Tagged as 'Wimp-4_70'

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.
