+/* 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).
