The mutable graphics path to change.
A pointer to an affine transformation matrix, or
NULLif no transformation is needed. If specified, Core Graphics applies the transformation to the arc before it is added to the path.
The x-coordinate of the center point of the arc.
The y-coordinate of the center point of the arc.
The radius of the arc.
The angle (in radians) that determines the starting point of the arc, measured from the x-axis in the current user space.
The distance the arc should travel (in radians). A positive value indicates a counter-clockwise arc in the current user space.
The angle to the second endpoint of the arc is calculated by adding the delta to the start angle.
