• Move(dist): move forward dist pixels
• Dot(): color the current position in current color
• LineTo(x,y): move and draw a line from current position
• Line(dx,dy): move and draw a line from current position
• Line(dist): move forward while drawing a line
• HLine(x1,x2,y): draw a horizontal line
• VLine(x,y1,y2): draw a vertical line
