Hmm I thought it support GL_TEXTURE_RECTANGLE natively.

This is making me think that my patchset is wrong in having
blitter/blit set the flag themselves on NPOT textures.

It might even be a good idea to split it in two flags, one for state
tracker->driver communication, and another for the driver->state
This way, r300g won't have to do anything.

Not sure on how to call the flags though, since the current name is
already too long.
