I've checked in changes now for Pango, GtkEntry, and GtkTextView so
all positioning and motion is now by graphemes.

You might want to try it out and see if it does what you want.
The one thing that may not be desirable for some languages is that
if you are sitting after a compound grapheme and hit delete, it
deletes the entire grapheme.

It may be desirable to make this configurable.. while I can imagine
that if you have a complex cluster in an Indic language you may just
want to undo the last typed key if you make a typo, Europeans will no
doubt not enjoy the experience of having ü<Delete> produce u.
