Transparent paint in Macdraw:
To create two circles, shaded with orthoganal parallel lines that
intersect in a cross hatch,  create the circles in macpaint individually,
and paste each one separately into MacDraw.  In MacDraw, MacPaint bitmaps
are each separate objects, AND they are transparent (they are drawn using
the srcOr drawing mode, rather than the srcCopy of native MacDraw
objects.)
Large bitmaps are not one object in MacDraw, but many objects.  Group them
as the first thing you do after the paste.  (Macpaint does this to
preserve a Mac User Interface Guidline rule: individual bitmaps shall be
small than 3k, so the application program won't die from a big bitmap
clobbering the stack.)
