[cairo] [PATCH] [cairo-gl] Fix support for gl window surface resizes (take 2)

[Alexandros Frantzis]

Hi all!

Now that the issue with surfaces and gl_contexts is hopefully clear, I
have created a new branch that includes Andrea's proposed patch.

This is a similar but improved version of my original
gl-window-surface-resize branch which has now been overwritten with a
new version.

The patches can be found in the 'gl-window-surface-resize3' branch at:

http://git.linaro.org/gitweb?p=people/afrantzis/cairo.git;a=shortlog;h=refs/heads/gl-window-surface-resize3

git://git.linaro.org/people/afrantzis/cairo.git

Summing up the current branch contents:

gl-window-surface-resize: use width/height to detect surface resizes
gl-window-surface-resize2: use a per surface serial to detect surface resizes
gl-window-surface-resize3: use a per surface flag to detect surface resizes

Thanks,
Alexandros
