something else which looks like it might contain this nicely is
the Magic Lenses research at xerox parc.

this can be looked at as a system of compositional transformational
filters, and gives a nice Open Implementations style to most of the
gui. There are as usual performance issues, but in a primitive
sketch I've put together using immutability to allow caching in thr
actual renderer makes it reasonable fast over CLX.
