              DeviceN colour space issue. Will need to investigate further as to what is the cause of the ordering issue.

              Unfortunately the fix breaks a bunch of other sample files we have. PDF-762 had his original fix attached to it, I'll need to revisit the issue to see if some sense can be made of this corner case related to our other samples.

              I have a fix for the missing red dashed boarder which is actually an image. The image is raw and falls back to our old parseImage legacy image code. The only problem is that the code has no support for 2 bit per component and the deviceN colour space. Most DeviceN falls under colour space component count of 4 regardless, so I've made a slight tweak to get the image to decode correctly. The old fall through code just writes a white pixel.
