[cogl/cogl-1.16-gst: 12/15] cogl-gst: Add some documentation

commit 5f86563c86e9d449b0d9864783bccde4af9792d4
Author: Neil Roberts <neil linux intel com>
Date:   Wed Apr 24 19:43:00 2013 +0100

    cogl-gst: Add some documentation
    
    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.

+/**
+ * SECTION:cogl-gst-video-sink
+ * @short_description: A video sink for integrating a GStreamer
+ *   pipeline with a Cogl pipeline.
+ *
+ * #CoglGstVideoSink is a subclass of #GstBaseSink which can be used to
+ * create a #CoglPipeline for rendering the frames of the video.
+ *
+ * To create a basic video player, an application can create a
+ * #GstPipeline as normal using gst_pipeline_new() and set the
+ * sink on it to one created with cogl_gst_video_sink_new(). The
+ * application can then listen for the #CoglGstVideoSink::new-frame
+ * signal which will be emitted whenever there are new textures ready
+ * for rendering. For simple rendering, the application can just call
+ * cogl_gst_video_sink_get_pipeline() in the signal handler and use
+ * the returned pipeline to paint the new frame.
+ *
+ * An application is also free to do more advanced rendering by
+ * customizing the pipeline. In that case it should listen for the
+ * #CoglGstVideoSink::pipeline-ready signal which will be emitted as
+ * soon as the sink has determined enough information about the video
+ * to know how it should be rendered. In the handler for this signal,
+ * the application can either make modifications to a copy of the
+ * pipeline returned by cogl_gst_video_sink_get_pipeline() or it can
+ * create its own pipeline from scratch and ask the sink to configure
+ * it with cogl_gst_video_sink_setup_pipeline(). If a custom pipeline
+ * is created using one of these methods then the application should
+ * call cogl_gst_video_sink_attach_frame() on the pipeline before
+ * rendering in order to update the textures on the pipeline's layers.
+ *
+ * If the %COGL_FEATURE_ID_GLSL feature is available then the pipeline
+ * used by the sink will have a shader snippet with a function in it
+ * called cogl_gst_sample_video0 which takes a single vec2 argument.
+ * This can be used by custom snippets set the by the application to
+ * sample from the video. The vec2 argument represents the normalised
+ * coordinates within the video.
+ *
+ * Since: 1.16
