That's correct, but I haven't used that. My reading is you can apply matrices to rotate and translate the texture mapping coordinates. For example if square is mapped to 0.45 x 0.45, 0.45 x 0.55, 0.55 x 0.55, 0.55 x 0.45 on x/y and you translate 0.1 on y, it'll "move" the texture down 0.1 so that the mapping is now 0.45 x 0.55, 0.45 x 0.65, 0.55 x 0.65, 0.55 x 0.55. Or you you rotate 90 degrees on the z axis it'll turn the texture on it's right side. Is this true?
