PR - Relative coordinate pen move
PR [X, Y [,...]] [;]
X ; X coordinate of the cursor movement destination
Y ; Y coordinate of the cursor movement destination
 Coordinates are relative to the current position in user units or graphics units.
 Plots a straight line only when the pen is down.
 When scaling has been performed, the cursor is moved by relative coordinates in user units.
 Also, when scaling has been performed, the values for X and Y are real numbers.
 When there is no scaling, the cursor is moved by relative coordinates in graphics units.
 When there is no scaling, the coordinate values for X and Y are integer numbers.
