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.

7 * \brief A way the modules can set up their own properties on objects.
8 *
9 * Properties are key-value pairs that are associated with objects.
10 * MadButterfly associate a property store for each object (coord or shape)
11 * to keep property values. Every property is identified by a ID; an
12 * integer. Programmer can use a ID to set/get value to/from a property
13 * store. The ID should be unique in a property store.
