SMask is unrelated to the bug and can be commented to simplify the test.

The bug is caused by 2 problems in Jasper.
1. Jasper silently converts 16-bit data to 8-bit data but PostScript
   expects 16-bit ones. This is easy to work around.
3. Lab data returned by Jasper have unexpected format. I didn't figure
   out yet what it is. I any case, it is now what [/Lab ...] color space
