For example: I have a 64x64 4-bit texture and I want to repeat it over a
960x64 polygon. I.e. 15 times, there was a thread in the 3D newsgroup about
it but it didn't specify how to set up the U V coords, I'm pretty sure by
reading that post that it can be done, at least one person did it anyway (I
think).
