I personally am really looking for the latter, plus (in an ideal world,
obviously:-)) a guide to how the "new" core pipeline works, since I'm
afraid I've found it a little tricky to trace some things which might be
bugs (I'm not sure) through the 3.1 and later cores.

Thanks. Am I right in assuming that what I would learn from looking at
the DRI drivers would apply to builds of Mesa that don't use accelerated
GLX or any direct equivalent (such as the FX driver built for Windows,
for example), while the Utah GLX source might be of less general
relevance? Or is this a stupid question?
Thanks again,
