fixtrx - Fix null tracks in a Viking image plane
"fixtrx" checks each of the 7 tracks in each line of a Viking image
plane to determine if it is a bad track.  If the threshhold of NULL
pixels is met or exceeded then that track is considered bad and all
NULL pixels in that track will be replaced using a 5 x 5 low pass
filter.
