This adds several utility apis that aim to make it as easy as possible
for an application to determine what size a video should be drawn at.
The important detail here is that these apis take into account the
pixel-aspect-ratio in addition to the video's own aspect ratio.
This patch updates the cogl-basic-video-player example to use the
cogl_gst_video_sink_fit_size() api to perform letterboxing.

Previously cogl_gst_video_sink_attach_frame returned the last layer
used by the sink. This can also be retrieved via
cogl_gst_video_sink_get_free_layer so I don't think it's necessary to
return it here and it seems kind of out of place.

These are just internal convenience macros to define the GObject
properties so they shouldn't be in the public headers.

Adds documentation comments to CoglGstVideoSink and makes it generate
a separate manual to contain it.
One thing that I wasn't able to figure out with this was how to get
the documentation to have correct references to the main Cogl docs.
You can pass arguments to gtkdoc-fixxref to point to other manuals,
but presumably this needs the installed locations and when the
Cogl-Gst documentation is generated the Cogl docs may not have been
installed yet.

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.
