ghostscript has a bug or two that i've encountered (the version on
fedora core 2) that causes blank pages to show in some circumstances.
forcing a redraw or specifying a device (-sDEVICE=x11) seems to fix it.
that kinda sounds like part of the problem you're seeing here. 

as for why things are only showing in the lower left-hand corner i'd
have to see do_draw () to be able to venture a guess there.
