Detail:
  cache_sprite_doesnt_exist_error routine in MsgCode failed to take into
  account the fact that the messages file might be tokenised. Calling
  MessageTrans_Lookup with R2=0 gives you the length of the unexpanded
  message in R3. Now fixed to work in a better way.
  Also rename fp to r11 in swiv2 file to avoid assembler warnings.
Admin:
  Soft-loaded module tested. Problem seems to be solved.


Version 1.17. Tagged as 'SprExtend-1_17'

C compiler that spots signed divisions of known-positive quantities (eg in
this case (<char>*254)/100), and does them as unsigned instead.

Version 1.16. Tagged as 'SprExtend-1_16'

First pass check now only looks for a SOI tag,not bothering looking
for the "JFIF" text: this lets both JFIF and EXIF files through the
first gate.
Next,improvements to the find_image_dimensions routine to properly
look for tags rather than assuming tag APP0 is always at the start of
the file as it is in ".jpg" files.Again - EXIF files are now understood
as a side effect,plus a nice speed up for when skipping unknown tags.So
rather than loading lots of unused 1k blocks it just sets the file
pointer forwards to the required point.
Tested with a handful of specially contrived EXIF files plus some frommy
Panasonic camera,plus retested the JPEGs in the ChangeFSI test directory
to check that progressive JPEGs are still correctly faulted.
Yay - !Paint and !Draw can now load digital camera piccies!

Version 1.15. Tagged as 'SprExtend-1_15'

* Transformed sprite plotting optimised to not read the screen memory when
  it could be simply avoided - greatly enhances performance on Iyonix.
* Decoding of 1x2 sampled JPEGs fixed.

Version 1.14. Tagged as 'SprExtend-1_14'

Replaced a couple of STMs in error recovery code with code sequences that don't use UNPREDICTABLE (and XScale-unsafe) instructions.

Version 1.13. Tagged as 'SprExtend-1_13'

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:
  Don't know why - probably didn't work with where they were?
Admin:
  Made this change months ago - can't remember anything else about it.


Version 1.10. Tagged as 'SprExtend-1_10'

Detail:
  This doesn't work because amu will (correctly) say that the semicolon
    is a command separator.  This is now fixed by passing each pattern
    separately with -e.
Admin:
  Not tested.


Version 1.09. Tagged as 'SprExtend-1_09'

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.
