Summary:                    vtkImageActor image shift
Description: 
Image is shifted by one or two pixels in vtkImageActor. It is observed in 5.8.0
and 5.10.0. When I tested it using a color picture then it looks like color
layers shift differently.

Attached is a test result using a 20x10 pixel BMP image (24bit, made in
PhotoShop) with some grids. Left image is the original image and the right image
is the image on vtkImageActor through the following pipeline. You can see a
strangely shifted image.

vtkBMPReader
vtkImageShiftScale
vtkImageShiftScale.SetOutputScalarTypeToUnsignedChar()
vtkImageData
vtkImageActor
vtkImageActor.InterpolateOff()
