That's not accurate though; we render in hardware, but to transform from
2D pixmap to 3D texture requires a copy through the CPU, which is of
course ridiculous. Fixing that will be much easier when we have a memory
manager shared between 2D and 3D, which is about the same time as we get
FBO support.

I've never seen this myself and I'm not sure what it means.
