Detailed Description

A heterogeneous pixel used to represent packed pixels with non-byte-aligned channels. Models PixelValueConcept.

Example:

   typedef packed_pixel_type<uint16_t, mpl::vector3_c<unsigned,5,6,5>, rgb_layout_t>::type rgb565_pixel_t;
   BOOST_STATIC_ASSERT((sizeof(rgb565_pixel_t)==2));

   rgb565_pixel_t r565;
   get_color(r565,red_t())   = 31;
   get_color(r565,green_t()) = 63;
   get_color(r565,blue_t())  = 31;
   assert(r565 == rgb565_pixel_t((uint16_t)0xFFFF));
