When unpacking 16 bit image data, unpack it all.
Ensure we don't miss the last one off. Differences appear on the right
hand edge of the images when rendering:
gs -dNOINTERPOLATE -o out-%d.psd -sDEVICE=psdcmyk -r300 -dMaxBitmap=10000 fts_02_0200.pdf
vs
gs -dNOINTERPOLATE --debug=memfill-empty -o out-%d.psd -sDEVICE=psdcmyk -r300 -dMaxBitmap=10000 fts_02_0200.pdf
