Summary0012679: Incorrect rendering with vtkImageResliceMapper after vtkImageClip
DescriptionThe vtkImageClip filter gives an output whose extent is larger than its whole extent. This confuses the vtkImageResliceMapper and seems to result in the following behaviour:
1) when rendering is done to a polygon, the polygon shape is incorrect
2) when rendering to the whole viewport (without a polygon) no cropping is done at all

Fixed in commit acb5b09dc5846116ee277334f684b24edbed184a

The bug was because the interpolation code was using the Extent for bounds checks instead of using the WholeExtent, so if the Extent was larger than the WholeExtent, the rendering would extend past the WholeExtent.
