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?
non-power-of-2 textures are supported on nearly all modern graphics
hardware up to 2048x2048 pixels, except for the old ATI Rage * variants
which only support Po2, up to 1024x1024.

* Pismo G3, most iBook G3, PB G4 400-667, B&W G3, G4 350-Dual 500,
maybe others.  Not sure about early iMac/eMac.

OpenGL is quite complex. For those of you just getting started with it, it is very handy to have A Big Chart Of What Is Supported Where And Links To All The Specs: http://homepage.mac.com/arekkusu/bugs/GLInfo.html


For figuring out what video card shipped in a given Mac, apple-history.com is relatively complete.
