Description

File is from
https://storage.googleapis.com/google-code-archive-source/v2/code.google.com/lumi-read/source-archive.zip
and can be found in lumi-read/trunk/PDF_smoketest/pdf/image_via/image_via_1.3_006.pdf

The color edges of the lower image are interpolated but should not be. Solution: respect the image interpolation setting in PDImageXObject.scaleImage().
