202 * Draws a line from (hpos, vpos) to (hpos+dx, vpos+dy), and leaves the current
208 if ( dx == 0 && dy == 0 )
210 else fprintf(tf, "%d %d %d %d Dl\n", hpos + dx, vpos + dy, hpos, vpos);

633 * new baseline. Equations for x(t), y(t), dx/dt, and dy/dt must be written in
636 * last one on the stack, while the equation for dy/dt comes last (in *buf) and
750 * dy/dt = g'(t)
753 * first (ie. it ends up on the bottom of the stack) and the equation for dy/dt
