   Does anybody out there have code for fast area fills using the blitter?
I have been putting together a program that has been rendering a large number
( >100 ) of multi-colored polygons in real time.  At first I sent each poly
to Area...() separately ( Called AreaEnd() between each 2 polys ) but that was
too slow.  Then I only called AreaEnd() at the end of each frame, but all I
got was a mono-chromatic blob, although the rendering speed more than doubled.
In the last version, I separated the colors and rendered them separately, but
the frame rate is not much better than the first method.

   I am on the point of junking GfxBase and poking around in the blitter
myself, so I would appreceate (sp?) any ideas on how to sort lines so when
they are filled, the colors go in the right places.
