Emmanuele Bassi e934ad03ca Add ClutterCairoTexture
Move the ClutterCairo actor from a separate library to an in-tree
actor.

ClutterCairoTexture is a simple texture subclass that allows you
to retrieve a Cairo context for a private image surface. When the
Cairo context is destroyed it will cause the image surface
contents to be uploaded to a GL texture.

The image surface used is not hardware accelerated.
