[cairo] [PATCH] [cairo-gl] Fix support for gl window surface resizes

[Bill Spitzak]

You could also put a serialize number on the surface that is incremented 
when the size changes and test that. This reduces the number of tests 
and the storage needed by the cairo_t, and allows more things than the 
width and height to trigger this code without more expense.
