- Code please? It doesn't mean anything if you don't know HOW to program
- fast graphics under 3.0... (and you don't, most likely, since MOST people
- don't have any documentation on 3.0 as of yet).

- Again, graphics.library isn't gonna help you much if you insist on using
- old routines in slow ways.

- We need blazing speed, not necessarily optimized assembly. Two different

-
- Depends on what you're doing... I'd suggest that you optimize the way you
- USE graphics.library, not the way graphics.library is written.
