Attached is an updated version of
the "rgbadraw" work in imlib2 that I sent earlier.
Though I've included all files for
completeness, the update only addresses the
"polygon.c" and "ellipse.c" files there.
The poly changes are to deal with
the issue of horizontal edges, and the ellipse
changes are to fix an oversight.
There are still many things here that
could be improved -- and I'm afraid that I'm
running out of time for it ...
