Ah, I was sharing the representation between the two widgets, and that
just doesn't make any sense. I guess I was thinking of the
representation like a glyph, but it actually contains information
about the interaction history. I guess I never understood why the
widget and representation (and in this case, another layer, the
Handle) are so separate?
