imagetoraster: Completely black page when CMYK TIFF is input

[LXY1226]

Describe the bug ArgyllCMS's cctiff generated CMYK tiff produces completely black pages in imagetoraster. And the tiff is displayed correctly in gimp and windows.

To Reproduce Steps to reproduce the behavior:

1. Get a cmyk tiff a. get ffmpeg and ArgyllCMS b. use ffmpeg to convert an image to tiff ffmpeg -i test.png test.tif c. use cctiff in argyllcms to apply rgb -> xyz -> cmyk operation cctiff test.tif argb.icc cmyk.icc test_cmy.tif tip: all will be provided at bottom of this article include a cmyk icc for example. tip: the linux binary provided by ArgyllCMS will produces broken tiff on my machine. so try it under windows or just download my sample.
2. try to print it though cups by command line lp test_cmy.tif tips. You can try my script to use imagetoraster only and use rasterview to validate this in order to preserve inks :<
