Subject: RISC OS SDL Patches
Sam, I've attached a diff of the latest changes to libSDL for RISC OS
support. These changes are by Alan Buckley and myself.
The most significant of these are:
Optimised assembler blit rountines - I've attached the file
src/video/riscos/SDL_riscosASM.s which is needed for this.
Move to using /dev/dsp instead of its own audio implementation.
This means that src/audio/riscos/SDL_drenderer.c should be removed
Typo fixes. Mainly correct spelling of "RISC OS", but some from elsewhere
too.
