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 situation 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.
