Oh, but that's only the name!
The trouble is that window classes have a lot of attributes --
styles, background brushes, etc. -- that are all shared across
instances.
There is currently no way (that I know of) to allow a subclass to
define its own attributes, *without* also giving it a chance to
define them per-instance instead of per-class.
