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

     Transform a distance vector from user space to device space. This
     function is similar to 'cairoUserToDevice' except that the
     translation components of the CTM will be ignored when
     transforming ('dx','dy').

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

     cairoUserToDeviceDistance(cr, dx, dy)

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

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

    'dx': [numeric]  X component of a distance vector (in/out
          parameter)

    'dy': [numeric]  Y component of a distance vector (in/out
          parameter)

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