Belt printer: classic tree branches land on the belt instead of sliding down it

Browse Source 
TreeSupportData added the belt surface to every layer's outlines, so the
belt fed the classic tree's collision and avoidance maps.  A node that
descends onto an obstacle is pushed out of it, and on a belt that walked
the branch down the tilted surface, ahead of the part, before it could
end: tree hybrid/slim/strong supports swept far along the belt where
organic supports dropped straight down.  Take the belt out of the
outlines.  The belt is where a branch ends, and that is already handled:
drop_nodes() stops a node once its whole circle is in the belt
(belt_node_landed()) and draw_circles() clips every layer's circles to
the belt plane, so the branch tapers to a tip on it.
