Regarding a software implementation: what if we did like OS X and compile GLSL
to i386 (or what you will)?

Maybe this does not seem like less work, but I think a lot of it has already
been done for us. Zack Rusin who works on Mesa has been using LLVM to do this
[1] (as OS X does [2]). What's more, the GLSL parser for LLVM is already (at
least partially) written. The repository that had the original code mentioned
in [1] appears to be down now, but I believe its merged in to Gallium3D [3].

I've looked through wined3d in an attempt to figure out if this could be easily
done, ignoring the issue for now that the referenced GLSL parser is in C++, but
as I have no prior experience I am afraid I have little to show for my efforts.
There was at one point a software renderer [3], though unfinished, so perhaps
putting in another could follow that as an example? Yet that was relatively
long ago, and the code has changed. Unfortunately, I also have little
experience with gl, so I am a bit unsure of the if/how for getting at the data
needed when mixing software processing with the gl processing on hardware like
this.

Could Stefan or someone else who knows better comment?
