New version from Kevin: OS_SpriteOp 55 and 56 can take top-bit-set translation table pointers, at the expense of the condition for no translation table being tightened to either 0 or -1 (previously documented as <= 0). This is the version included in release 5.00 of the OS.

Version 1.12. Tagged as 'SprExtend-1_12'

Used to interpret negative translation table pointers as "none"; now just 0
as per documentation.
Plotting 16bpp sprites into 32bpp modes now correctly sets the 3 least
significant bits of each channel - used to be set to 0 due to a typo.
Build option (currently set to on) to use SMULL instructions.

Version 1.11. Tagged as 'SprExtend-1_11'

Detail:
  The build structure for this module is not nice - I've sanitised it a
    bit, but it's still not nice.
Admin:
   Built and tested with the test program briefly - the test sprite seems
     to scale and rotate properly.  ChangeFSI not tested.


Version 1.08. Tagged as 'SprExtend-1_08'

  Addition of srccommit files.
Detail:
  * c.jrdjfif, get_dqt had an empty debug loop when debug was disabled.
    This is no longer compiled when debugging is not enabled.
  * VersionNum and VersionASM files added, and Sources.SprExtend modified
    to use symbols exported from there rather than from Version.
Admin:
  Ran on my machine. Previously tested in ROL builds.
  In future, might like to merge Exif support from ROL builds, but don't
  want to do that until I've re-read the specs on Exif format again.

Version 1.07. Tagged as 'SprExtend-1_07'
