    Fix for Bug 692553; SEGV in fast thresholding halftoning code.
    
    Stupid C got the % operation wrong.
    
    In this instance, it gives an unexpected negative value causing out of
    bounds offsets. Simple fix is to offset by the period if it's negative.

Changed files:
gs/base/gxht_thresh.c

Products tested: gs ls pcl xps 


New warnings:

None
