Sorry to disappoint -- I'm really pleased to see someone make a start on
this.

I don't know how important it is to have this *and* the identity layer
-- the only real point for identity was as a template for building new
layers.  Now, if someone wants a new layer, they could start with your
sanity module & strip out all the checking.

It's a bit of a pain having lots of layers hanging around as they add
work to the already fairly tedious process of introducing interface
changes.  While I think we're mostly done with that now (modulo Roland's
array texture branch), I think it probably makes sense to prune a couple
of the less-useful layers we have hanging around.
