>/* XXX: In cairo 1.2.0 we added a new %CAIRO_FORMAT_RGB16_565 but
> * neglected to adjust this macro. The net effect is that it's
> * impossible to externally create an image surface with this
> * format. This is perhaps a good thing since we also neglected to fix
> * up things like cairo_surface_write_to_png() for the new format
> * (-Wswitch-enum will tell you where). Is it obvious that format was
> * added in haste?
> *
> * The reason for the new format was to allow the xlib backend to be
> * used on X servers with a 565 visual. So the new format did its job
> * for that, even without being considered "valid" for the sake of
> * things like cairo_image_surface_create().
> *
> * Since 1.2.0 we ran into the same situtation with X servers with BGR
> * visuals. This time we invented #cairo_internal_format_t instead,
> * (see it for more discussion).
> *
> * The punchline is that %CAIRO_FORMAT_VALID must not conside any
> * internal format to be valid. Also we need to decide if the
> * RGB16_565 should be moved to instead be an internal format. If so,
> * this macro need not change for it. (We probably will need to leave
> * an RGB16_565 value in the header files for the sake of code that
> * might have that value in it.)
> *
> * If we do decide to start fully supporting RGB16_565 as an external
> * format, then %CAIRO_FORMAT_VALID needs to be adjusted to include
> * it. But that should not happen before all necessary code is fixed
> * to support it (at least cairo_surface_write_to_png() and a few spots
> * in cairo-xlib-surface.c--again see -Wswitch-enum).
