Missing indication of resize areas

[deni]

When the user moves the mouse over a resize area (for a frame or sticky), it should change its color. In this way the user will know that he/she can drag the area to resize the element.

• Modify SceneInteractionLogic to change the mouse over element of the scene appropriately
  • Currently, the mouseoverElement property of the scene is updated only if the event source of the new mouseover element is different than the event source of the old mouseover element.
  • This should be changed.
  • However, MOUSE_ENTERED and MOUSE_EXITED events should be fired only when the event source changes.
• Instead of adding 8 different resize areas in each view of a resizable element, create a class that contains them all and add an object of this class (according to the implementation review of bug #1242).
  • Create an inner class of ResizeAreaSceneElement called ResizeSubAreaElement extending DefaultShapeSceneElement and move the position property, the contructor and the setup method that computes the area shape there.
  • Leave the inner and outer bound rectangles in ResizeAreaSceneElement, because they are common for all 8 subareas.
  • Make ResizeAreaSceneElement extend DefaultCompositeSceneElement.
  • Override setupSceneElements in ResizeAreaSceneElement to add the 8 different subareas.
  • Use a map to cache the subareas and avoid creating new ones every time (like in FrameView).
  • Make FrameView and StickyView consistent with this design.
• ResizeSubAreaElement should take care to change its colour when the mouse is over it.
  • Add a new autoproperty in ResizeAreaSceneElement for the scene that contains the resize element. Its compute method should call an abstract method subclasses will implement.
  • In a setup method in ResizeSubAreaElement check whether the mouseover element of the scene is this, and if so, set the filling to green color. Otherwise, set the filling to transparent.
