- That's obviously not true. If I told them how to build the bomb

- Replace "hobby programmers" with "c0d3rz that never listen".
- Replace "want to prove" with "state facts that".

- Right. It depends on lots of things, so at least a straight
- copy can be optimized by the driver.

-
- which isn't necessarily applicable if your graphics system
- has DMA channels that bypass the MMU.

-
- Do they ? I thought they wanted a hunk of chipmem to poke to and
- a copper list.

-
- Maybe there is, maybe there is not. I'd rather have well-optimized code
- in the driver than half-guessed c0d3r-stuff.
