  31.      the type declarations of their parameters and whether or not they assume
  32.      a two- or three-dimensional space.

  38.      _d_y   expects the distance from the y coordinate of the current graphics
  39.           position to the y coordinate of the new point.

  75.      rrrrddddrrrr is the relative version of ddddrrrraaaawwww.  It connects the current graphics
  76.      position and a point, at the specified distance, with a line segment
  77.      using the current linestyle, linewidth, color (if in depth-cue mode, the
  78.      depth-cued color is used), and writemask.  The system updates the current
  79.      graphics position to the new point.
  80.  
  81.      Do not place routines that invalidate the current graphics position
  82.      within sequences of relative moves and draws.
