Is it important for textures (in video ram) to have heights of 1<<n? I realize a width of 1<<n (i.e. 256, 512, 1024 etc) is important, but is it OK to have a height of say, 768? I can understand the video hardware needing a width of 1<<n to allow for quick computation of texture addresses (given x and y), but can't see the importance of having the height be a 1<<n. I can understand a height requirement of 1<<n, should there be texture wrapping on the Y coordinate, but I'm not doing that. So what do you think, is it a bad idea to have texture sizes of say, 512*768px?
