That was one fun weekend, getting that worked out. My initial cut just used
a single variable to keep track of self. I found out the hard way that a
callback (such as an onPaint) can trigger at any time, and when you return,
self has been mangled. Using a stack to keep track of the state takes care
of that problem.

Yet another minor detail to add to the list...
