I know a pfBillboard isa pfGeode in libpf, and a pfSprite isa pfObject in libpr,
and that a pfBillboard is an implementation of a pfSprite. I am working on a
particle system and would like to know:

1. The difference(s) between, and limitations of, a pfSprite and a pfBillboard
2. When it would be advantageous to use one versus the other
3. What is the minimum hardware requirements for any optimizations implemented
in hardware.

Thanks.
