Basically FXImage is an image - whereby you can alter it by drawing
on it, or modifiying its bitmap directly. If you were to make copies
into a list, it would be sure slow.
I think the best solution might be for it to return a wrapper class
which provides operator. This may in fact solve all my problems.

Agreed, cheers for the help. I'll try hacking together some code to
do this tomorrow, and if acceptable it might be an idea for pyste.
