- Use a single `lab_scene_rect` for both overlay background and outlines,
like I described in the TODO comment in ffd4005.
- Simplify the resource management by destroying the overlay tree when
it's hidden. I think its overhead is pretty minimal.
- Share a single `lab_scene_rect` for both region/edge overlays.
