The vertical line count is used for positioning the display areas vertically
and it is initialized at the new field boundary. The vertical line count is
used to compare with the start and end rows of each display area and
increments with each horizontal sync. In some timing systems
(i.e., NTSC), the vertical line count does not initialize to a value of one.
For NTSC and PAL systems, the Vline Count Init value in Register 282
