Here's a little program I've been using to exercise alpha channel
blending.  It draws a bunch of overlapping circles in various colors
on various backgrounds.  I'm not sure the displayed results are
correct, but maybe that's an artifact of my 8-bit display, and it's
pretty slow, but debugging aside (I'm running with some patches to
libdraw from Russ), I thought it would make a nice little example of
the new graphics model.
