The functions aren't defined, nor have pointers.  For instance:
*       Scaling/rotation        box '((0,0),(1,1))' * point '(2.0,0)'

I see how it can be scaling (or shearing), but how does it do rotation?
Or maybe when the points x^2+y^2 == 1, it's interpreted at rotation?
Each operator needs a full explanation...
thx
