Detailed Description

This tests stacking. It also shows how to use b2World::Query and b2TestOverlap. This callback is called by b2World::QueryAABB. We find all the fixtures that overlap an AABB. Of those, we use b2TestOverlap to determine which fixtures overlap a circle. Up to 4 overlapped fixtures will be highlighted with a yellow border.
