A side effect of this seems to be that Filled Circles drawn with the
ArcFillMode (I think that's it), are weird at the edges.  In particular,
if you draw two filled circles, (complementary, in opposite colors), as
the boundary moves, you get leftover dots.  Pretty annoying, particularly
when doing the same thing on most hardware graphics boxes (directly, not
using X), doesn't have that problem.

By the way, are said pixelation rules different/better in X11R4 than X11R3?
We don't have R4 yet (from HP), so I was kind of hoping the problem was
at least reduced???
