It initializes the "X Toolkit" environment; Motif is a widget set built
atop the "X Toolkit", but GTK+ is a widget set not built atop the "X
Toolkit".  Not all X-based toolkits use the "X Toolkit".

The way to initialize the GTK+ environment is to call "gtk_init()".

If Middleware makes calls to routines with names beginning with "Xt",
it's not going to handle all X-based applications, it's going to handle
only applications using "X Toolkit"-based widget sets such as Motif, not
non-"X Toolkit" based widget sets such as GTK+ or Qt.
