_c_a_i_r_o_C_l_i_p

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

     Establishes a new clip region by intersecting the current clip
     region with the current path as it would be filled by 'cairoFill'
     and according to the current fill rule (see 'cairoSetFillRule').

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

     cairoClip(cr)

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

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

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

     After 'cairoClip', the current path will be cleared from the cairo
     context.

     The current clip region affects all drawing operations by
     effectively masking out any changes to the surface that are
     outside the current clip region.

     Calling 'cairoClip' can only make the clip region smaller, never
     larger. But the current clip is part of the graphics state, so a
     temporary restriction of the clip region can be achieved by
     calling 'cairoClip' within a 'cairoSave'/'cairoRestore' pair. The
     only other means of increasing the size of the clip region is
     'cairoResetClip'.
