Sets the attributes of the reusable {@link Arc2D} object that is used by
{@link #drawArc(int, int, int, int, int, int)} and
{@link #fillArc(int, int, int, int, int, int)} methods.

@param x  the x-coordinate.
@param y  the y-coordinate.
@param width  the width.
@param height  the height.
@param startAngle  the start angle in degrees, 0 = 3 o'clock.
@param arcAngle  the angle (anticlockwise) in degrees.
