Rather than keeping it and enabling deprecated code in testgtk I decided
to delete the example. The warnings from testgtk about deprecated code
are too useful IMO.
Should we need it again, we can make it into its own test, or add a
testgtkdeprecated.

Those if() blocks don't have any reason being there, as x and y are not
pointers. If the window is destroyed, just set the out values to zero
and return.

gdk_unicode_to_keyval(uc) returning (uc | 0x01000000) is not an
error return value but simply the way to encode 24-bit unicode
characters directly as keyvals.
