[Mesa3d-dev] recent Mesa changes

[Brian P. <br...@pr...>]

1. I've moved the programs that used to be in 3Dfx/demos/ into the demos/
   directory since they're also suitable for other 3D hardware, not just 3dfx.
   If you update with 'cvs update -P' it'll prune away the dead 3Dfx/
   directory.

2. Holger Waechtler has implemented the GL_EXT_texture_env_combine extension.
   I applied his patch this afternoon.  Thanks, Holger!

3. Gareth Hughes implemented new functions for allocating memory on
   arbitrary memory alignment boundaries.  By aligning floating point
   arrays on 16-byte boundaries (for example) we should be able to make
   better use of caching and memory fetches with 3DNow and SSE instructions.
   It might even help in tiny bit in ordinary x86 FP code too.
   Thanks, Gareth!

This has all been checked into the 3.3 trunk.

Please report any problems ASAP.
