Corrects accidental dropping of pixel residue.

Browse Source 
Specific issue: the repeated (start_column != end_column) test, which can no longer be correct if start_column has been incremented in the (x_&7) test.

The visible effect was to omit pixels from the output wave, which also affected observed sync timing.
