Description
Reported by Liguo Wang
This bug also affects images with large area of dark region such as images of a grid square. The grid bar region appears speckled as some pixels have much higher intensity than what is expected of a dark region

This is a GatanK2 specific bug. It was introduced when the early GMS 2.3 version failed system correction when image was rotated or flipped.
r18556 fix this in trunk
r18557 fix this in 3.0
r18558 fix this in 3.1
This bug affects the integrated image but not normalization of the frames in appion since apDDprocess.py does not use this.
Liguo, please let me know if this fixes the problem.
