     Gets the current scaled font for a 'Cairo'.

     cairoGetScaledFont(cr)

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

    'cr': ['Cairo']  a 'Cairo'

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

     Since  1.4

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

     ['CairoScaledFont']  the current scaled font. To keep a reference
     to it.

     This function never returns 'NULL'. If memory cannot be allocated,
     a special "nil" 'CairoScaledFont' object will be returned on which
     'cairoScaledFontStatus' returns 'CAIRO_STATUS_NO_MEMORY'. Using
     this nil object will cause its error state to propagate to other
     objects it is passed to, (for example, calling
     'cairoSetScaledFont' with a nil font will trigger an error that
     will shutdown the 'Cairo' object).
