Detail:
  s/Draw - Try using OS_ReadSysInfo 6 to get IRQsema before falling back on the legacy address. Store pointer in workspace for speedy access.
Admin:
  Tested on rev A2 BB-xM


Version 1.21. Tagged as 'Draw-1_21'

Detail:
  Version - Now uses Hdr:CPU.Arch to decide whether to enable long muls or not
  s/Draw - Extra GETs for Hdr:CPU.Arch
Admin:
  Tested in Iyonix & IOMD ROM softloads


Version 1.20. Tagged as 'Draw-1_20'

Detail:
  Draw 1.18 and earlier versions return a corrupted value of r0 from
  Draw_ProcessPath when called with a non-0 matrix pointer in r2. That
  affects both the SWI return value in case of success and the error pointer
  in case of an error, which means that
  (a) using Draw_ProcessPath to find out the required output buffer size
      returns a corrupted value for the required buffer size.
  (b) using Draw_ProcessPath to process the path returns a corrupted value
      for the path end pointer.
  (c) if an error occurs (most notably, "Output buffer full") during
      processing a corrupted error pointer is returned, which typically
      leads to crashes in the caller when trying to dereference it.
Admin:
  Tested by softloading on Iyonix RO514.
  Fix provided by Martin Wuerthner.

Version 1.19. Tagged as 'Draw-1_19'

Detail:
  CPU version is no longer specified in the makefile - it's better to inherit
  it from the build environment now that we actually set it appropriately.
Admin:
  Built but not tested. Binary should be unchanged - this only affects the
  warnings generated during assembly.

Version 1.18. Not tagged

Detail:
  Uses suffixed file extensions for compatiblity with both objasm and asasm.
Admin:
  Supplied by Peter Naulls, tested at ROOL

Version 1.18. Not tagged

Spotted by Stephen Wigner, ticket #193

Version 1.18. Tagged as 'Draw-1_18'

Draw_ProcessPath moved into R1.
Patches - a simple programme to patch existing versions of Draw so that there
is no need to worry about having to check version numbers and no need to
ship a softloading module.

Draw_ProcessPath,R7,bit 31.
Now,bit 26 (ironic) of the flags word (crazy!) signifies that R7 is a
proper 32 bit value and bit 25 is now the flag that used to be in R7.
Setting these two flags on older versions results in a "reserved bits
not zero" error - but the changes made are small enough to allow older
modules to be patched.

Version 1.17. Tagged as 'Draw-1_17'

Will now selectively use OS_HeapSort32.Fixes bug report of data abort in the Kernel when closing a complex bezier curve (>30 points typically).

Version 1.16. Tagged as 'Draw-1_16'

  Updated to build using objasm instead of aasm.
  Sources changed to be objasm-compatible.
Admin:
  Requires Library 0.72 or later.
  Requires BuildSys 3.09 or later.
  Requires Env 0.65 or later.

Version 1.15. Tagged as 'Draw-1_15'

Detail:
  There was a conditional for the clip-to-path stuff that was used in
    Hdr:Draw and defined only locally in Version.  The conditional is
    now removed from the Hdr file, and the SWI name symbols added for
    the Stroke and Fill clipped SWIs. The Draw module will fall
    back to the unclipped versions if the macro is set false in the
    build.
Admin:
  Built.

Version 1.14. Tagged as 'Draw-1_14'

Detail:
  * Draw paths can be clipped against other Draw paths using an additional
    pair of SWI calls. Draw path clipping is by remembering the scan lines
    that would be used for the clip path and then clipping against those
    when plotting the draw path. Ick.
Admin:
  Very experimental, very nasty, but it works and does do the clipping.
  Can be conditionally removed.
