    7979The OpenGL specification requires implementations to support at least 32 entries on the transform stack, so you should be able to apply this many nested 'rotate' 'translate' and 'scale' transforms to your picture. If this isn't enough then you can probably refactor your program so it doesn't use so many nested transforms.

    81 This problem with a fixed size transform stack is discussed further in Section 4 of [http://www.opengl.org/archives/resources/features/KilgardTechniques/oglpitfall/ Overflowing the Projection Matrix Stack]. Gloss tries not to use the stack when it doesn't have to, but we don't know of any way to spill the stack to main memory to allow more entries. If you know how to solve this problem without giving up on hardware acceleration and doing the transforms in software, then please let us know on the mailing list.
