present: Add window flip mode
In contrast to screen flip mode this mode: * supports flips per windows (these windows currently need to have the same size as their parent windows with the same pixmap), * sends pixmap idle signals to the client only after the driver has given an additional event notify. This patch only introduces the new mode as a stub. It additionally needs a driver hook, such that it can get initialized and appropriate cleanup functions.
