Maybe a long time ago this made some kind of sense, but now there's no good reason to ever use this, rather than the Shadow DirectDraw NonLocking engine. Also remove screen private data members used by other removed engines. Also remove no longer needed OS version check in winDetectSupportedEngines() Signed-off-by: Jon TURNEY <jon.turney@dronecode.org.uk> Reviewed-by: Colin Harrison <colin.harrison@virgin.net>
