/**
 * 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
