That is already done for the ddraw window itself, but of course not for
the other windows (dialogs and its controls) for which the game expects
certain _PAINT messages. Do you think we can set pixel format on all the
windows owned or created by the application when going exclusive
fullscreen mode, or am I missing something? I am not yet sure how that
could work for a general case as in theory application could have set
some pixel format explicitly on some windows and expect that to be
preserved.
