Fix mouse handling for render model

Before we use a tricky way to share mouse event between model render widget and model edit widget, which forward the event from render widget to edit widget. This will cause some problem, such as the scroll bar of edit widget would not work when it covered by the render model.
Now the mouse event is totally disabled in the render widget, and when there is a need we forward it from edit widget.
