Thanks for the encouragement. It's done, and a patch submitted against
As it happened, I had to touch both gtkselection and gdkselection -- the latter because of the text conversion routines. Fortunately in OSX, there is only utf8 for strings (unless someone overtly codes something else, but why do that?), so the implementations were pretty simple.

I found in my studies that the Gtk widgets don't use the selection interface at all anymore; they use GtkClipboard. There's a recommendation about that in the Gtk Selections documentation, but I suggest going all out and deprecating the selection interface.

Yes, I understand that redesigning Gdk would be a long term goal. Have there been any discussions about what the architecture would look like on IRC? I sure haven't seen any here...
