I was under the impression that Mesa already had ARB_vertex_program and
ARB_fragment_program implemented; are you referring to the docs needed
to implement shaders in Mesa using the native hardware shader architecture?
Going forward, I don't really see any of the major players (read: nvidia
and ATI) becoming any more "open source" friendly, as far as hardware
documentation goes -- we'll probably be stuck with proprietary drivers
for some time now, fairly good ones in nvidia's case, and horrid ones in
The question then becomes whether purely software Mesa can be fast
enough to deliver a desktop based on the features that glitz wants to
use, so that it can be considered "baseline functionality", no?
