Let doors and trapdoors occlude in hulls

Browse Source 
Doors and trapdoors do not occlude for the client, so they had no full face
in the hull and rays passed through closed trapdoors, revealing blocks behind
them along diagonals. Their face masks now come from their shape, so the face
their panel covers is full.
