\brief Class describing a plane geometry.
The plane geometry specifies the half-space volume x<=0. As with other geometry types,
when used in a PxShape the collision volume is obtained by transforming the halfspace
by the shape local pose and the actor global pose.
To generate a PxPlane from a PxTransform, transform PxPlane(1,0,0,0).
To generate a PxTransform from a PxPlane, use PxTransformFromPlaneEquation.
