plscmap1 - Set opaque RGB cmap1 colors values

r (PLINT_VECTOR(3plplot), input)
              A vector that represents (using unsigned 8-bit integers in the range from 0-255) the degree of red
              in the color as a continuous function of the integer index of the vector.

       g (PLINT_VECTOR(3plplot), input)
              A vector that represents (using unsigned 8-bit integers in the range from  0-255)  the  degree  of
              green in the color as a continuous function of the integer index of the vector.

       b (PLINT_VECTOR(3plplot), input)
              A  vector  that  represents  (using unsigned 8-bit integers in the range from 0-255) the degree of
              blue in the color as a continuous function of the integer index of the vector.

       ncol1 (PLINT(3plplot), input)
              Number of items in the r, g, and b vectors.

       long history.

       Set  opaque cmap1 colors (see the PLplot documentation) using RGB vector values.  This function also sets
       the number of cmap1 colors.  N.B. Continuous cmap1 colors are indexed with a floating-point index in  the
       range  from 0.0-1.0 which is linearly transformed (e.g., by plcol1(3plplot)) to an integer index of these
       RGB vectors in the range from 0 to ncol1-1.  So  in  order  for  this  continuous  color  model  to  work
       properly,  it is the responsibility of the user of plscmap1(3plplot) to insure that these RGB vectors are
       continuous functions of their integer indices.

       Redacted form: plscmap1(r,g,b)

       This function is used in example 31.
