What is more work is what I talk about farther down in my previous e-mail.
It is possible to create a stencil primitive that works something like:
`(replacement-skylines ,left ,right, ,up ,down original-stencil)
but that seems kludgy. It would be better and more consistent with currently
practices in the code base if stencils carried their own skyline information
(as they do their own dimensions), which would require a lot of juggling code
around.
