- then they it is no C2P function any more ;)
-
- use writepixelarray8 on gfx-cards, own c2p routines on chipset.
-
- BTW:
- imagine an AGA+ chipset with chunky mode.
- what to do if you want to render directly to chipmem ? (maybe it's lot
- faster, and maybe it's still the only mem on future lowend amiga).
-
- writepixelarray8 will do unessesary copying...
-
- BTW: does writeparr8 destroy source when using gfx-cards ?
