Here are two things I'd really like to be able to do in MacDraw; if
there is some way to do them, please let me know!
1.  Suppose you are drawing Venn diagrams, two intersecting circles,
one with horizontal cross hatching, the other with vertical, and
the intersection with checkerboard hatching.  Hmmm, can't do it!  You
need transparent paint...  
2.  Same situation, but we want the intersection to be gray, instead.
Hmmm.  We need to be able to define an object which is the intersection
of two objects, put it in front, and shade it.  This is easy enough if
our original objects are polygons, but circles?  Better get out the
Xacto knifes...
