Slightly shortens NTSC frame.
...
Either: (i) 263 is incorrect; or (ii) my logic as to frame height is incorrect. Given that the horizontal side of things is really well documented, I'm currently guessing (i). Research to do.

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.
