[PD] GEM: routing gemheads

[David Powers]

Hi fellow PDers,

If I have, say, a single gemhead that ends with a [pix_texture], how
can I make some kind of switch to map that gemhead onto different
stuff. ie, in one case it goes to a normal rectangle, in another case,
it maps onto some abstract polygons, etc...

The basic idea is that in my interface I will toggle between the
different texture mappings on the fly with keystrokes once the switch
is built.

Thanks for any help!
