040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync * ShadowFBInit initializes the shadowfb subsystem. refreshArea is a pointer
040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync * to a user supplied callback function. This function will be called after
040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync * any operation that modifies the framebuffer. The newly dirtied rectangles
040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync * are passed to the callback.
040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync * Returns FALSE in the event of an error.
040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync * ShadowFBInit2 is a more featureful refinement of the original shadowfb.
040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync * ShadowFBInit2 allows you to specify two callbacks, one to be called
040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync * immediately before an operation that modifies the framebuffer, and another
040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync * to be called immediately after.
040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync * Returns FALSE in the event of an error
