[cairo] YUV / RGB images

[Gerdus van Zyl]

I have used DevIL/OpenIL (openil.sourceforge.net) to good effect
before when trying to convert/read images that are not png.
For an example of working with cairo see http://cairo.pastebin.com/f1fbd86ff

Cairo's image surface buffer is in BGR(a) I seem to recall from past
list messages; see the cairo API docs for
cairo_format_stride_for_width for a small example.

That being said gstreamer is pretty awesome and easy if you have to do
anything with video.
