It's definately something to keep in mind. But until the hardware
is available we've got plenty of other things to accomplish so I'm
not going to worry too much about it right now.
Ideally when the hardware does transformation most of the API entry
points will practically map right onto the hardware. What could make
it a mess is if the hardware only implements _some_ of the OpenGL
transformation features. Then a mix of hardware and software paths
will be needed. Yuck.
