[vtk-developers] vtkBoundedPlanePlacer problem

[dean.inglis at camris.ca]

Hi,

there were some changes made to vtkBoundedPointPlacer for the 
new vtkParallelopipedWidget that does not appear to allow
for simple placement on bounded 2D planes and breaks the functionality
of vtkImageActorPointPlacer .  Can anyone verify by 
drawing on an image with vtkContourWidget and then trying to move 
the widget's handles.  See script below...
