Detail:
  s/Tiling, s/Tiling3D, s/Watchdog, s/Wimp05, s/Wimp07, s/Wimp09 - Replaced OS_SpriteOp reason code magic numbers with symbolic definitions.
  s/Wimp01 - Update *WimpMode / Wimp_SetMode to use OS_ScreenMode 13 (mode string to specifer) in place of its own code if a mode specifier string has been given. Note - mode number handling is unchanged, so a mode specifier string which begins with a mode number will currently have the specifier part ignored.
  s/Wimp01, s/Wimp02 - Flag_* -> ModeFlag_* renaming
  s/Wimp02 - Fix mode specifier copying to only stop copying when we hit a mode variable of -1. Previous code would also stop if the variable value was -1. Update mode set code to apply the Wimp's special greyscale palettes if the greyscale mode flag is set (i.e. greyscale mode was set via specifier generated by OS_ScreenMode 13)

Version 5.31. Tagged as 'Wimp-5_31'

Detail:
  Unnecessarily complex code in Watchdog for killing tasks other than the
  currently active task ended up corrupting the environment handlers for
  the current task.
Admin:
  Fixes the test case of running a BASIC program consisting of
    REPEAT UNTIL FALSE
  which previously caused random errors or complete crashes if you ran it
  and then Al-Breaked and tried to kill a different task.

Version 5.01. Tagged as 'Wimp-5_01'

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'

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:
  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'

* If pointer was hidden-until-next-mouse-move, the act of confining the mouse
  to the error box window no longer causes it to be redisplayed.
* In error boxes, the pointer and the IconHigh highlight are now initially
  positioned over the rightmost (default) button. There is one exception to
  this rule: when "Next task" is clicked in a Watchdog window, the pointer
  stays over the "Next task" button.

Version 4.13. Tagged as 'Wimp-4_13'

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'
