gl-renderer: Obscure protected content on unprotected display

Browse source 
The content protection protocol requires that in enforced mode, parts of the
surfaces which lie on outputs with protection level lower than that of the surface
be censored. This patch uses a solid shader to color such regions with
dark red.
