Sorry; I should have pointed out that I didn't want case-insensitivity.
For example, I'm leaving the GL constants all caps (and want to do this
to help people distinguish btw functions and constants).
E.g. (gl-matrix-mode gl-PROJECTION)

  Also, I just thought people might be interested in more general 
transformations via the "easy FFI".
