BR, Bezier Relative
This command draws bezier curves using relative coordinates. This
command uses the current pen position as the first control point, and
specifies the other three control points as relative increments from the
first point.
BR X1,Y1, X2,Y2,X3,Y3,...[X1,Y1, X2,Y2,X3,Y3]]
The BR command uses the current pen location and three specified
control points to draw a bezier curve. After each new Bezier, the last
control point of the previous curve becomes the first control point of
the next Bezier. All curve control points are relative to the first control
point of that curve. For example, points 1, 2, and 3 of the example are
relative to the starting point, while points 4, 5, and 6 are relative to
point 3.
