CVS Update (optimized blits)

SDL Development
1

A bunch of fixes are in the latest CVS snapshot:
http://www.devolution.com/~slouken/SDL/cvs.html

  • Not being able to set audio frags is no longer fatal
  • Added support for multiple timers (thanks Stephane Peter)
  • Copy blits optimized using inline assembly on x86 Linux
  • Copy blit can now handle overlapping blits
  • Fixed GL direct rendering on Utah GLX (thanks John Fulmer)
  • Re-enabled X11 backing-store - doesn’t affect speed.

Please test the audio code to make sure it’s not broken.

Thanks!

Maybe not, but did you get any visible benefits from backing store?
It isn’t a question of speed directly, but wasted memory. Decreasing
memory pressure is always a good thing. I don’t think backing store is
worth the memory it takes under SDL (even if it is usually < 1 Meg),
since you’re working with memory buffers, not drawing primitives.
