I'd just expand on the PROP_TYPE_LIST.  It's not used anywhere yet, and it
has some of the infrastructure laid out for it.

StdProp inheritance?  I don't think we really have any of that.

Oh, you mean object inheritance.  You can look at how, say,
Object/zigzagline inherits from OrthConn, that should show most of the
issues.  One thing we can't do at the moment is remove properties in a
subclass in a simple (i.e. not just copying properties) manner.
