 - Outlines: Mask out the inner mesh that is being outlined to avoid inner outlines.
 - X-Ray: Display a mesh behind other objects.
 - Portals: Draw geometry that is normally "impossible" (non-Euclidian) by masking objects.
-- Shadows: Draw sharp shadows without relying on shadow maps.

-    You can only read stencil in the transparent pass.
-    Any attempt to read in the opaque pass will fail, as it's not supported behavior.

     Also, stencil operations aren't yet supported in compositor effects.
