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

     Converts a 'PangoGravity' value to its natural rotation in
     radians. 'gravity' should not be 'PANGO_GRAVITY_AUTO'.

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

     pangoGravityToRotation(base.gravity)

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

'base.gravity': ['PangoGravity']  gravity to query

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

     Note that 'pangoMatrixRotate' takes angle in degrees, not radians.
     So, to call 'pangoMatrixRotate' with the output of this function
     you should multiply it by (180. / G_PI).  

     Since  1.16

_V_a_l_u_e:

     [numeric]  the rotation value corresponding to 'gravity'.

_A_u_t_h_o_r(_s):
