One of the display limitations I felt of Khoros was that the print
pixel values function showed the display color and the display pixel
intensities - not the true pixel intensities.   A slight modification
to run_pixels.c in src/xvroutines/editimage was all that is needed.

The diff is shown below.  

In editimage, Print Pixel Values now prints the true pixel value but only
when in grey mode.
