other people have posted already on the below, so I'll just add - you
can of course just pad out your arbitrary texture rectangles to powers
of 2, and then use UV coords in the appropriate range.
e.g. if your texture is 80x80, pad it up to 128x128 and then use uvs in
the range (0, 80/128)
I've a notion that on some cards using the NV_TEXTURE_RECTANGLE
extension is less efficient for texturing use, but I've nothing to back
that up off the top of my head.
cheers,
os.

A question to OpenGL AUViewers... do you still have to make texture
bitmap sizes n x n pixels where n is a power of 2? Or is there a way to
use n x m pixels at arbitrary length?
