Besides making these functions much nicer to use, this fixes a number of things: - Clients now don't have to free the returned structures. - The ScreenInfo allocated by XineramaQueryScreens should be freed with XFree, not p_delete. This patch also introduces an abstract Area type that will be very useful.
