Would be nice to be able to handle these as an enum in a switch.  Not sure if
Dart helps you much there though.

You might actually want a dots model, which has changed callback of sorts which
can do the markNeedsPaint and then these individual handlers don't need to think

eventually these will be class "is" expressions, which Dart definitely doesn't
do in a switch yet.
