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?
If you want arbitrary sized textures, you should use the
GL_TEXTURE_RECTANGLE_EXT extension. Off the top of my head it is
available on almost all modern GPUs (if it supports Quartz Extreme you
should be good) and it changes your texture coordinates to be n x m
instead of 1x1.

Failure is not an option. It is a privilege reserved for those who try.
