Hah - must be something in the air! Now that I have a (mostly) working
computer again, I'm rewriting all the DHTML mouse handling code to use a
single div for grabbing mouse events.
It's one of those changes that keeps getting larger as I keep finding
code/edge cases to throw away.
Anyway, please try to avoid any heavy work on the DHTML kernel until
this is done....

User-defined<type>s want to extend the schema with new (javascript) classes (that

need to disentangle ViewSchema from ClassModel so that I can re-use ClassModel for both
kinds of classes and extend either the schema's tags or types. The disentangling mostly
involves moving a lot of methods that are in ViewSchema (that take an element as an
argument, look up its ClassModel, and then call back into the ClassModel to compute the
answer) into ClassModel. Which greatly simplifies things, because you already have a
handle on the model. It turns out there are lots of predicates that ViewSchema is
computing from scratch on the DOM that can be computed once and cached in the model.
Anyways, try not to pull the rug out from under me... I have a big pile of
changes in play, moving methods around.
