    Then there are the point-plotting displays like the one on the
LINC and its descendents.  In those, it's all intensified points on
the screen, and those have to be refreshed continually else the
medium-persistence phosphor fades completely out.  But that's off-
topic here other than pointing out that there is more than one way
to skin a cat.
