SF: Fix a defect in the layer filtering logic

Change 32cbe2 broke the layer filtering logic when moving it over to
CompositionEngine. It would allow certain layers to appear on a virtual
display when they were supposed to be filtered out.

This corrects the logic to be what it was supposed to be, and adds a
unit test that verifies and documents the expected behavior.
