The code pushed upstream doesn't have any layer separation yet. It is
present (hard-coded separation though), in my own repo.or.cz development
repositories, along with various tricks and hacks to make the 3D
rendering MUCH faster than currently upstream.

That code has never got upstream because it is still in a horrible messy
tangle of refactoring. I also vaguely recall having got stuck half-way
into redesigning various internal drawing interfaces within the new
code, not really knowing which direction I should take the final API.

It certainly needs cleaning (and the upstream drawing interfaces gently
refactoring to match) before it can be merged. The main issue is (as
usual), my bandwidth - which is approximately 0 at the moment out side
of work.


OTOH.. I have been reading (for fun) some VERY interesting books on 3D
BREP modelling recently... I am starting to become tempted once again to
play with some of these ideas.
