Made some progress on this one.

The main image is 16bpp CIELAB jpx for which the interface to jasper has a
problem in computing the stride.  Jasper does decode the image correctly as 16
bits.  Fixing the stride, it is clear that we have some issues with the head
and 16 bit ICC support.  Working on that right now.  Should have something
shortly.

Also, I have a fix that properly handles the jpeg2000 enumerated color spaces. 
When I get all of this in place, I will post a patch for review as it involves
changes in the pdf interpreter.
