[Cogl] [PATCH] Include CoglGst

CoglGst is a GStreamer integration library that facilitates
video playback using the Cogl API. It works by retrieving
each video frame from the GStreamer pipeline and attaching
it to a Cogl pipeline in the form of a Cogl texture along
with possible color model conversion shaders. The pipeline
is then retrieved by the user during each draw. An example
use of the CoglGst API is included in the examples directory.
