  //       Class : CollisionHandlerQueue
  // Description : A special kind of CollisionHandler that does nothing
  //               except remember the CollisionEntries detected the
  //               last pass.  This set of CollisionEntries may then be
  //               queried by the calling function.  It's primarily
  //               useful when a simple intersection test is being made,
  //               e.g. for picking from the window.
