Example:

   typedef packed_frame_type<uint16_t,
                             mpl::vector3_c<unsigned,5,6,5>,
                             rgb_layout>::type rgb565_frame_t;
   BOOST_STATIC_ASSERT((sizeof(rgb565_frame_t)==2));

   rgb565_frame_t r565;
   get_channel(r565,red_t())   = 31;
   get_channel(r565,green_t()) = 63;
   get_channel(r565,blue_t())  = 31;
   assert(r565 == rgb565_frame_t((uint16_t)0xFFFF));
