TV2COLOR
Type:  Verb
Use:   Interactive function to pseudo color the sum of all visible TV
       images.  There are two methods implemented.  The first method
       consists of 2 colors as "linear" functions of intensity
       increasing away from a central point.   The cursor X position
       controls the location of the central point and the Y position
       changes the "gamma" correction made to the linear coloring
       values.  High Y values make softer colors, low makes the colors
       harsher with a deeper minimum.  Hit button A or B to switch the
       colors used in a loop through the 6 possibilities.  Hit button
       C to switch to the second method.

       This second method also uses two colors separated by a central
       point.  The two colors are separated by 1/2 of a turn in hue.
       The cursor X position controls the position of the central
       point.  The cursor Y position controls the color saturation
       with higher Y positions producing more saturated colors.
       Hit button A to swicth both hues by 1/12 of a turn.  Hit
       button B to select whether the intensities are constant or
       increase away from or toward the central point.  Hit button
       C to return to the first, pure-color method.

       Press button D to exit.

Adverbs:
  OVERLAP...Fractional overlap of the 2 colors in the first method.
  TVLEVS....Specifies the maximum intensity expected for the sum of
            all visible, overlapped images.  Has always been n x max
            in one image (now 2046).  < 2046 => 2046.
