 Need a collection of standard shapes.  Try to use the existing path
 mechanisms whenever possible (the existing Box type is a bad example of
 the sort of thing that should be done, and should be removed and replaced
 with a path-based version).

 An (inexhaustive) list of the shapes that should be available: regular
 polygons of any number of sides; 45-45-90 triangle; 30-60-90 triangle;
 stars parameterized by number of points and perhaps other size/shape
 parameters; rounded rectangles; rounded polygons in general.
