Comment (by danielk):

 (In [7569]) References #512.

 This implements a basic chromakey OSD.

 For it to be enabled, you must have this in your
 xorg.conf "Devices" section:
     Option "XvmcUsesTextures" "false" # use 3d engine for overlays
 And you have to insert a "UseChromaKeyOSD","1",hostname setting in
 the settings table.

 This currently makes no claim to efficiency, this clears the a
 buffer to the chromakey color w/borders, and then plops the OSD
 on top of it; creating an RGB OSDSurface or creating a specialized,
 chromakey painting, OSD blend function would probably be much
 faster. What this does make a claim to is not being too disruptive
 to the rest of the code.
