11  * Porting to GTK+ was done by:
12  *
13  * (C) 1998,1999,2000 by Marcin Dalecki <[email protected]>
14  *
15  * With GREAT support and continuous encouragements by Andy Kahn and of
16  * course Bram Moolenaar!
17  *
18  * Support for GTK+ 2 was added by:
19  *
20  * (C) 2002,2003  Jason Hildebrand  <[email protected]>
21  *		  Daniel Elstner  <[email protected]>
22  *
23  * Best supporting actor (He helped somewhat, aesthetically speaking):
24  * Maxime Romano <[email protected]>
25  *
26  * Support for GTK+ 3 was added by:
27  *
28  * 2016  Kazunobu Kuriyama  <[email protected]>
29  *
30  * With the help of Marius Gedminas and the word of Bram Moolenaar,
