[PATCH 0/3] MR5823: Quartz' basic fullscreen fallback.

[eric pouech (＠epo)]

A game creates a vmr7 filter, inserts it in a IFilterGraph2 and
calls put_FullScreenMode(OAFALSE) on the graph's IVideoWindow.

This currently returns E_NOTIMPL in Wine and the game quits
on that error code.

A full solution would likely require to implement IFullScreenVideoEx
filter, and other bits, but this simpler approach let the game move
forward.

Also tested & fixed calling put_FullScreenMode on the current mode
returns S_FALSE instead of S_OK.
