rollover and mouseover

This example demonstrates the difference between rollover / rollout and mouseover / mouseout events. The red and blue squares are separate Shape instances within a parent Container. The Container has both rollover/rollout and mouseover/mouseout events.

Note how the mouseover/mouseout events are triggered whenever you move between different display objects (ex. moving from the blue to red shape), but the rollover/rollout events are only triggered when you leave the Container's aggregate contents.
