commit 75e6d734c1b831e11831270d1777b84b689dca6a
Author: Robert Bragg <robert linux intel com>
Date: Fri Feb 25 11:29:08 2011 +0000
Add a vtable of indirection to the winsys code
So that we can dynamically select what winsys backend to use at runtime
we need to have some indirection to how code accesses the winsys instead
of simply calling _cogl_winsys* functions that would collide if we
wanted to compile more than one backend into Cogl.
