Summary0008269: vtkImageStencil fails if vtkPolyDataToImageStencil is outside of image
DescriptionWith VTK 5.2 release the stencil either produces wrong croppings or produces access violations if the polydata used to create the stencil is outside of volume/image bounds.

Additional InformationSteps to reproduce:

change line 237 of ImageTracerWidget.tcl :
isw ClosedOff
to:
isw ClosedOn
...to make the tracer widget always close the spline (a closed path doesn't
update the spline).

Start the script.
In the left window draw something like a circle but don't close it, it will
automatically close the spline on the right side.
No move the spline outside the image:
When moving up or down all is correct, but moving left right (outside of the
image) produces wrong cropping (or crashes). This bug was not in VTK 5.1
(cvs nightly).

 I've tested as described in the bug report (against VTK 6) and could not reproduce. I suspect that it was fixed by one of the following commits several years ago. The code has changed extensively since the bug was reported.
