Put this another way:  instead of having the common stencil code drive
the backends, the backends should use the common code if and when they
find it useful.  Common code could include font listing functions,
tree folds, and other traversal combinators.

Rather than arbitrary Scheme expressions, stencil leaves would
describe their contents.  This will often look pretty similar, but it
gives tremendously more flexibility to the backend, particularly in
how it chooses to implement coordinate transformations, but also in
how it deals with fonts.
