mutter/src/backends/meta-screen-cast-virtual-stream-src.c
Georges Basile Stavracas Neto 91bdb2b692 screen-cast/src: Track paint phase 
Track where we are in terms of the paint cycle. Do this through an
enumeration that is passed through the paint vfuncs of screencast
sources.

Right now, this information is not used by any one of the sources,
but next patch will use it to prevent blitting when detached from
the paint cycle.
