I always thought the restrictions on async pageflips were pretty
horrendous and wasn't sure if it would not cause rebinding our buffers
just when we wanted to flip as fast as possible.
As I look at it though, using SwapbuffersWait to force blits rather than
waits now doesn't preclude us from switching to async pageflips later.
