Painting gizmos and sinking objects:

Browse source 
1. Do not show what's below the bed when a gizmo is open
2. Triangulate the cut so people don't see inside
3. If regular clipping plane is used, the cuts are mutually clipped by one another
4. Painting itself ignores the hidden part of the object
