//       Class : PhysxCapsuleController
// Description : A capsule character controller.
//
//               The capsule is defined as a position, a vertical
//               height, and a radius. The height is the same height
//               as for PhysxCapsuleShape objects, i.e. the distance
//               between the two sphere centers at the end of the
//               capsule. In other words:
//
//               p = pos (returned by controller)
//               h = height
//               r = radius
//
//               p = center of capsule
//               top sphere center = p.y + h*0.5
//               bottom sphere center = p.y - h*0.5
//               top capsule point = p.y + h*0.5 + r
//               bottom capsule point = p.y - h*0.5 - r
