Thanks for this.

Overwriting the frame data?
I'd be worried this would cause memory leaks or similar weird issues when GTK 
tries to clean up the frame structure that's been scribbled over by the 
text_iter structure. Also we are praying that never 
sizeof(GtkTextIter) > sizeof (GtkFrame) 
However you imply that have used this technique in practice without problems, 
is that right?

I suppose you could immediately pass the frame object to gtk_text_iter_copy ()
which would give you a "real" text_iter memory allocation to use.
