Polymer: handle floor/ceiling translucency.

Assigns the right alpha value to floor/ceiling planes if their
translucency bits are set and make sure that changing the cstat now
triggers an update of the material for editing purposes.

This doesn't do anything by itself, but will be needed to correctly
draw floor/ceiling masks.
