Yes. Basically, take a look at the textured triangle functions
in src/triangle.c. By replacing the inner loop code with device-
specific code you can implement specialized rasterizers.
However, Mesa's software texturing has never been aggressively
optimized. There's all kinds of x86-specific tricks one could
use. I think Chris Hecker wrote some articles on this.

What are ya, lazy? :)
