Replaced use of LSL (et al) macros with the new myLSL macros to avoid
potential clash with new pseudo-opcodes

Admin: requires HdrSrc 1.79 or later.

Version 1.41. Tagged as 'SprExtend-1_41'

Since 2001 this module has been using objasm, but still using the C compiler to output (via -S) assembly code which is then passed through 'sed' and included via GET into the assembler code.
Changed to compile the C code into object files, and use the linker to patch up the unresolved references - this has required some reordering of the C code to make sure static functions now appear in the object file, and some reordering of the header files to ensure both the module and the CFSI version still compile without conflicts.
Minor fix to 'swiv2', the label was in the wrong place for _swi() though it's not used in this module so didn't affect the _swix() case.
Makefile cut down a bit. Unixify some path names.
Test code moved to 'Test/c' directory.
Tested in both debug and non debug cases via softloaded module. Oddly, it's 4 bytes longer than the previous version.

Version 1.28. Tagged as 'SprExtend-1_28'

Trim 200+ lines of changes dating back to 1987, combine with non duplicates in the 'BlackLog'.
Use 'offsetof' macro in genjhdr to avoid warnings about uninitialised variables, rename from makejhdr so all the utils are clearly demarked.
Add throwback to MkCFSI-j.
Replace reason codes passed to SWIs with textual equivalents from the respective header files.
Speed up SWI despatch a bit by making the first few debug instructions depend on 'debuggs'.
Qualify all of the debug switches with the global 'debug' one.
Eliminate single use of 'pullx' macro.
Make do_branch() take an unsigned opcode so 50% of the branches don't result in implied cast warnings.
Added an UNUSED() macro to reduce a few of the legitimate warnings (the remainder are either in the original JPEG code or ones that it is worth checking the logic of.
Unixify one last filename.

Version 1.24. Tagged as 'SprExtend-1_24'

Detail:
  The build utilities utils.makejhdr, utils.genpalette and utils.genyuvtabs,
  compiled at build time, are now built using the HostTools shared makefile,
  and so will execute on any RISC OS build host even if the default compiler
  options are to target an incompatible ARM architecture. Also now sets the
  throwback flag when doing builds via the Mk obey file.
Admin:
  Tested using an APCS-R build on an Iyonix.

Version 1.20. Not tagged

Detail:
  Creates install directories if not already present before doing the
  copy operation.
Admin:
  Will work.

Version 1.18. Tagged as 'SprExtend-1_18'

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.
