This is a nice patch.  For those who haven't looked at it, Dejan has used the
fact that linear transformations always transform a plane to a plane
to remove the 'current transform' variable from the plane object, and
has updated the transformation functions to directly modify the normal
and distance of the plane as appropriate.  This means that the intersection,
inside, and normal functions can be marginally faster for untransformed
planes, and significantly faster for transformed planes.
