Thomas Harte	253dd84109	Corrects accidental dropping of pixel residue. ... 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.	2019-11-17 18:34:13 -05:00
