Looks like it. At least for GL_NV_texture_shader, this isn't going to
happen, vmware needs to fix their code to use more generally supported
(and more useful) extensions instead. Not sure though it's actually
really required (note it says "Missing required extension" for some but
only "Missing extension" for others, so it might work just fine without

Though usually for most apps you don't really need it, you can just
enable "fake" support for it with driconf instead.

I've not yet tried the new unified i915 driver, but for the old i915tex
driver apart from mesa git (from a week or so ago) for the dri driver
you'd also needed drm from git, and a new enough 2d ddx driver (which
was built with that enabled).
