This represents the line number at the end of the top
horizontal bar. If 0, there is no horizontal bar.
This represents the line number at the beginning of a
lower horizontal bar. If greater than the number of active
video lines, there is no lower horizontal bar.
This represents the last pixel in a vertical pillar bar at the
left side of the picture. If 0, there is no left bar.
This represents the first horizontal pixel in a vertical pillar
bar at the right side of the picture. If greater than the
maximum number of horizontal pixels, there is no
vertical bar.
