I have isolated my infinite loop problem to the calls ccl:set-fore-color
and ccl:set-back-color which are called by my view-draw-contents method.
Calling these functions from inside the method apparently triggers the
event which calls the method again, and so on.
So how am I supposed to draw many objects, all of different colors, with
one invocation of the view-draw-contents method? Color does not seem to
be a property of the pen, like the pattern is.
