Benjamin Otte 4aac0760b3 wayland: Rewrite Cairo rendering 
Also, split it into its own file - which was the original reason for
looking at this code, the rewrite was an unintentional side effect.

This changes the context to create surfaces on demand.
So whenever the compositor holds onto a surface while GDK wants to
render, it just creates a new surface. If the compositor releases
surfaces, we will retain one for the next frame to be rendered, but free
all extra ones.
This way, we should get to a stage where we have exactly as many
surfaces as needed and never allocate/free any.

* some amount of control over the placement of our surface, and we can
* semi-accurately control the x/y position of these surfaces, if they are
* relative to another surface.
*
* To pretend we have something called a root coordinate space, assume all
* parent-less surfaces are positioned in (0, 0), and all relative positioned
* popups and subsurfaces are placed within this fake root coordinate space.
*
* For example a 200x200 large toplevel surface will have the position (0, 0).
* If a popup positioned in the middle of the toplevel will have the fake
* position (100,100). Furthermore, if a positioned is placed in the middle
* that popup, will have the fake position (150,150), even though it has the
* relative position (50,50). These three surfaces would make up one single
* fake root coordinate space.
