DESCRIPTION

rdr is the relative version of the draw command.  It connects the current graphics position and the point at the specified distance away with a line segment using the current linestyle, linewidth, color (if in depth cue mode, the depth cued color is used), and writemask.  The current graphics position is updated to the new point.  Commands that invalidate the current graphics position should not be placed within sequences of relative moves and draws.
