This makes sure we install a cogl-gst-1.0.pc and
cogl-gst-2.0-experimental.pc file consistent with other sub-libraries
such that cogl-1.x packages can be parallel installed with cogl master.

These functions are used when attaching frames at a start point other
than layer 0 is required. This could potentially be used to "layer"
videos and textures on top of each other in the CoglPipeline. This
layering could come handy if videos are used as alpha masks or normal
maps, or when arranging layers in a perticular order, so Cogl could
blend them nicely without extra hassle.

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.
