Detail:
  Fix out-by-1 error in MakeCompactModeWord, the palette checksum read from array index -1 due to the loop construction.
  Consider the x/y size as well as the compact mode word when deciding whether to recache the backdrop sprite.
  Don't assume the screen byte size is equivalent to working out the sprite byte size, due to word rounding at the end of each line. Calculate it properly.
  Allow the Wimp_SlotSize to exactly equal the required memory (previously, had to be larger).

  Submission from Timothy Baldwin, with minor refactoring.

Version 1.03. Tagged as 'Pinboard-1_03'

Fix for not recalculating pixel translation on backdrop tile going from G256 to C256 (or G16 to C16) mode specifier

The change in Pinboard-0_95 to get eigen factor rescaling right included a quick exit when neither the bpp nor eigen factors had changed.
However, changing from a greyscale to colour 8bpp or 4bpp mode falls fouls of this (since bpp and eigen are the same), so the backdrop sprite was not recached.
There was code to collect Message_PaletteChanged, however the Wimp hasn't sent this round since pre RISC OS 3.60, additionally the mode change code was manually disabling it (not required since Message_ModeChange was never accompanied by Message_PaletteChange according to PRM3-230). This has been switched out.
Now, the 'have I already done this sprite' flag includes the bpp and eigen factors plus a 13 bit hash of the desktop palette.

Version 0.96. Tagged as 'Pinboard-0_96'

Pinboard keeps a note of the mode (from OS_Byte 135) that the backdrop sprite tile was last cached in, to avoid having to recache it all the time. However, the comparison fails when the mode specifier block (ie. when OS_Byte 135 is not reporting a numeric screen mode) is static since although the mode might have changed Pinboard would not think it had and hence not recache the sprite.
The result is a patchy desktop, for example changing from EX1/EY1 to EX0/EY0 would leave a quadrant arrangement of 1 redrawn patch and 3 not redrawn.
Backdrop.s:
Line 151 onwards, when a mode specifier is used, build a magic mode word combining EX EY and BPP (the 3 parameters the cache sprite function cares about), as a stronger check.
Tail.s:
Line 130 onwards, calculate the iconbar height properly (previously used 134 pixels for EY0 modes, 1 too high, leading to a thin strip of background colour above the iconbar.
Other changes
 - Use sprite area offset names from Hdr:Sprites rather than magic numbers
 - Use OS_Byte reasons from Hdr:OsBytes
 - Use "file.s" style names in LNK commands
 - Move BadOptions/NotASprite error blocks to avoid range error when assembling debug versions
 - true and false for objasm {TRUE} and {FALSE}

Version 0.95. Tagged as 'Pinboard-0_95'

Detail:
  s/Backdrop - The tidying up in revision 4.8 caused a vital "MOV r0,#-1" to be lost, causing the wrong mode to be used when fetching the screen BPP. As a result, caching the sprite would fail if the sprite was in a lower BPP than the current screen mode, as the calculated sprite area size would have been too small. This fixes that.
Admin:
  Tested on rev A2 BB-xM.
  Sprite backdrops now seem to work again.


Version 0.94. Tagged as 'Pinboard-0_94'

When BootResources$Path is unset the option to run the configure plugin is no longer available.
Shared a "Filer_Run " string in 3x places.
Replaced most occurrences of calling XOS_ReadModeVariable of the current mode's XEig and YEig factors to use the cached copy sitting unloved in the workspace. Should thrash less during redraw.

Version 0.93. Tagged as 'Pinboard-0_93'

Same binary as 0.92, not tagged.

Same binary as 0.92, not tagged.

A few TEQ Rn,#0 changed to use 'S' and save an instruction.
Fix for misscaled tiled backdrop sprite in EX/EY0 mode - an 'out by 1'
error meant that some of the background colour shone through when the
tile sprite got resized to be too short.In any other EX/EY mode you never
noticed it due to rounding errors in the scaling.
The "Iconise to..." options submenu is now shaded if the Wimp has the
iconise buttons turned off: this minimises confusion for anyone who
hasn't realised that shift-close and iconise are subtley different in that
only the iconise button obeys the "Iconise to..." options,whereas
shift-close iconises at the point of application.

Version 0.81. Tagged as 'Pinboard-0_81'

Prefixed the pin and addtinydir commands that get saved in the
pinboard file with "X " so your pinboard setup continues even if a file
is no longer available.ROL did this with a new XPin command,not taken.
Merged changes from ROL to allow the icon text to be an arbitary colour
though this can be switched out with "technicolour_text" for the
purists.
Help entry added to the pinboard selection submenu,this will be greyed
out except when
 it's an app
 and it has a !help file
 and it is the only object selected
like the filer does.
Updated messages file accordingly.
Menu clicking on the "save pinboard settings" OK button no longer saves
the file,and adjust clicking keeps the menu tree open
 -> fixes bug report from 1998,now removed from "Status" file
Saveas template resized to match !Edit.
Fixed problem of select dragging a file to an app leaving the icon
selected (due to two conditional MOV R0's being followed by an
unconditional one for some reason).
 -> fixes bug report from 1998,now removed from "Status" file
Tweaked a few CMP#0 BLT's to test specifically for the iconbar handle.
The bug report in "Status" about bits of filenames being left on the
pinboard can be bodged by popping an ADD r0,r0,#16 after the XWimp_TextOp
in s.buffered but I've not done this yet.

Version 0.78. Tagged as 'Pinboard-0_78'

  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 0.76. Tagged as 'Pinboard-0_76'

Added inclusion of Machine header for new CMOS header
Moved to srccommit.
Templates contain hardwired version/date information which is a long
  way out of date.  This has not been fixed in this checkin.
