Jeff, this is a relatively discrete change, I can’t imagine it’ll have much
effect on you.

Support all the types in selection-converter-out-alist on GTK.
src/ChangeLog.GTK addition:
2011-08-26 Aidan Kehoe <kehoea(a)parhasard.net>
* device-gtk.c:
* device-gtk.c (gtk_init_device):
* device-gtk.c (vars_of_device_gtk):
At startup, tell GTK that we're capable of and interested in
passing selections for all those selection types in
selection-converter-out-alist. This means that we now support
non-Latin-1 data when copying and pasting, which previously wasn't
the case on GTK.
Call va_run_hook_with_args, don't reimplement it ourselves.
Remove Qgtk_seen_characters in passing, nothing was using it.
* select-gtk.c (emacs_gtk_selection_handle):
Fix a bug in this function; because of X11, the fifth argument to
lisp_data_to_selection_data is not the number of octets at the
address DATA, rather the number of elements, each of size FORMAT
bits, in the array at that address.
* select.h:
device-gtk.c now needs to see selection-converter-out-alist.

‘Iodine deficiency was endemic in parts of the UK until, through what has been
described as “an unplanned and accidental public health triumph”, iodine was
added to cattle feed to improve milk production in the 1930s.’
