Summary:                    vtkImplicitPlaneRepresentation ignores
NormalToZAxis, NormalToYAxis, and NormalToXAxis
Description: 
I can't be sure what the intent was here; my assumption is that the intent was
to lock the representation to axis-normal.  It appears that these instance
variables are unused (apart from being set/unset) in the class.  If the intent
is to force the representation to always be axis-normal, two things are needed.
1)  In the method SetNormal(double x, double y, double z) we need something like
	if(this->NormalToXAxis) x=1.0; y=0.0; z=0.0;
	if(this->NormalToYAxis) x=0.0; y=0.0; z=0.0;
	if(this->NormalToZAxis) x=0.0; y=0.0; z=1.0;
2)  Also in the methods SetNormalTo?Axis we need something like
  if (this->NormalToXAxis != var)
    {
    this->SetNormal(1.0,0.0,0.0);  // no effect, but SetNormal needs to be
called
    this->NormalToXAxis = var;
    this->Modified();
    }

There is another oddity with this class reported here 
http://public.kitware.com/pipermail/vtkusers/2010-January/105856.html  The way
the code is currently structured, one must SetBounds that include the plane
BEFORE doing SetOrigin and SetNormal, or they have no effect and are defaulted
to {0,0,0} and x-normal.

Additional Information: 
Some of this may be due to me misinterpreting the intent of the class.
