[Mesa-dev] instanced drawing branch

[Brian Paul]

I've pushed my draw-instanced branch.  It implements 
GL_ARB_draw_instanced in gallium, mesa tnl/swrast and the GLSL compiler.

There's a new register file type for "system values", both in Mesa and 
gallium/TGSI.  I'd like to change the front-face fragment input to be 
a system value at some point too.

I'll be off for the next two weeks and probably won't do anything more 
with this until the new year.
