68000 can clear a word every half a microsecond. blitter can do it at least
twice as fast, I believe. Probably more.
No, you can't just clear the bitplanes onscreen to draw a new polygon, because
you don't want to lose the existing data that was underneath your new polygon..
ie: there may have been 10 other polygons underneath, and you want them to
still be there!
