EPhysics: add test that exposes collision issues
When objects move fast collision detection fails. We need to expose an way to configure collision detection so user can optimize usage for her use case. Also it leaves the canvas dirty sometimes. We need to verify that as well. TODO: make theme for spinner and shoot button SVN revision: 73247
