the way I was doing inheritance between the display and editable scene
implementations was not copacetic. The new method (which is for every
editable scene impl to delegate to a display scene impl so that regardless
of how far along you are on the inheritance chain, there are only ever two
actual objects, the display impl and the editable impl) is somewhat
cleaner, but makes it clear that no method can work as nicely as it would
were we to have mutliple inheritance.
The basic problem is that the editable versions of the scenes have to be
able to manipulate the instance variables in the display versions of the
scenes because they have to keep them up to date so that they are
displaying the right thing. As the editable versions are in different
packages, they don't have access to the display instance variables, so the
display versions simply have to make available enough "editable"
functionality to allow the editable versions to get their job done. It's
more coupling that I'd like, but at least it's only between the display
and editable versions across the inheritance hierarchy rather than down
the hierarchy.
Blah.
