\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.

@see PxShape.setGeometry() PxShape.getPlaneGeometry() PxTransformFromPlaneEquation
