    GTK: simpler text scaling under Cairo
    
    Rather than constructing a transformation matrix piece by piece (with
    very branchy code), draw_stretch_before now just calls cairo_translate()
    and cairo_scale() with values that are almost-obviously correct.
    
    Also, rather than stashing and restoring the transformation matrix
    ourselves, it seems simpler to use cairo_save() and cairo_restore().
    That requires that draw_stretch_before() and draw_stretch_after() be
    called strictly in pairs, but they are so that's OK.
