_c_a_i_r_o_A_r_c_N_e_g_a_t_i_v_e

_D_e_s_c_r_i_p_t_i_o_n:

     Adds a circular arc of the given 'radius' to the current path. 
     The arc is centered at ('xc', 'yc'), begins at 'angle1' and
     proceeds in the direction of decreasing angles to end at 'angle2'.
     If 'angle2' is greater than 'angle1' it will be progressively
     decreased by 2*M_PI until it is less than 'angle1'.

_U_s_a_g_e:

     cairoArcNegative(cr, xc, yc, radius, angle1, angle2)

_A_r_g_u_m_e_n_t_s:

    'cr': ['Cairo']  a cairo context

    'xc': [numeric]  X position of the center of the arc

    'yc': [numeric]  Y position of the center of the arc

'radius': [numeric]  the radius of the arc

'angle1': [numeric]  the start angle, in radians

'angle2': [numeric]  the end angle, in radians

_D_e_t_a_i_l_s:

     See 'cairoArc' for more details. This function differs only in the
     direction of the arc between the two angles.
