If your texture is mapped on to a geometry and yopu want the texture
transformations to be local, then you can use pre and post DRAW
callbacks. In the pre callback, you load your transformation matrix onto the
texture matrix stack after saving the previous state, and in the post
callback, you restore the stack.
