However this also meant that it wouldn't modulate with the default colour. This patch changes it to set the combine mode on all of the layers to REPLACE(PREVIOUS) so that it just copies the previous layer without generating any texture sampling. That way the fragment snippet for the final layer can just modulate the previous value with the video sampling function. This makes it possible to set a color on the pipeline and have it modulate the video. Also if we eventually add a way to insert layers before the GST sampling layer then it can modulate with those.

cogl-gst: expose aspect ratio apis 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.
