X backend only sent EVT_MOUSE_MOVE_RAW to MadButterfly. - backend does not interpret mouse events (over/out/move), now. - redraw manager, now, interpret mouse events to make it backend independent. - The task (interpret mouse events) should be moved to somewhere in futhure. - backend only sent MotionNotify as EVT_MOUSE_MOVE_RAW. - EVT_MOUSE_MOVE_RAW is interpreted by backend independent code.
