Summary: Remove al_wait_for_vsync()
Initial Comment:
al_wait_for_vsync() for some drivers waits for the vsync in addition to the the flip command waiting for vsync, resulting in FPS = 1/2 refresh rate of the screen. I can see this happen in ex_prim which uses al_wait_for_vsync(), where FPS is exactly 30. It becomes 60 if I remove al_wait_for_vsync() . This problem was predicted in this thread http://www.allegro.cc/forums/thread/598066 , where the decision was made to remove it and make it a display creation hint. Submitting a bug report so this is not forgotten.

This was fixed at some point via the ALLEGRO_VSYNC hint + documentation in
al_wait_for_vsync.
