Thou hast been bitten by that most egregious of monsters, the Immense
ClipRect.  When you create the grafport that you draw into to generate
the picture, always set it's cliprect to just surround the area that will
be drawn.  Otherwise you get a huge cliprect (-32768,-32768,32767,32767)
and the scrapbook and other programs go a little bonkers because of it.
