/*
 * Porting to GTK+ was done by:
 *
 * (C) 1998,1999,2000 by Marcin Dalecki <martin@dalecki.de>
 *
 * With GREAT support and continuous encouragements by Andy Kahn and of
 * course Bram Moolenaar!
 *
 * Support for GTK+ 2 was added by:
 *
 * (C) 2002,2003  Jason Hildebrand  <jason@peaceworks.ca>
 *		  Daniel Elstner  <daniel.elstner@gmx.net>
 *
 * Best supporting actor (He helped somewhat, aesthetically speaking):
 * Maxime Romano <verbophobe@hotmail.com>
 *
 * Support for GTK+ 3 was added by:
 *
 * 2016  Kazunobu Kuriyama  <kazunobu.kuriyama@gmail.com>
 *
 * With the help of Marius Gedminas and the word of Bram Moolenaar,
 * "Let's give this some time to mature."
