Creates new circle arc shaped sub-path. The arc center is at (cx, cy), the arc radius is r,
and the arc is drawn from angle a0 to a1, and swept in direction dir (NVGWinding.CCW, or NVGWinding.CW).
Angles are specified in radians.
Arguments: [cx, cy, r, a0, a1]*
mode is: "original", "move", "line" -- first command will be like original NanoVega, MoveTo, or LineTo
