The atoms that GTK+ uses are not the same as the actual
atoms on the display ... this is for multihead reasons,
largely ... GTK+ might be connected to different displays
at the same time and the same atom in GTK+ needs to correspond to a
different atoms on each display.
>From gdkx.h:
GdkAtom gdk_x11_atom_to_xatom_for_display (GdkDisplay *display,
GdkAtom atom);
GdkAtom gdk_x11_xatom_to_atom_for_display (GdkDisplay *display,
Atom xatom);
Atom gdk_x11_get_xatom_by_name_for_display (GdkDisplay *display,
const gchar *atom_name);
G_CONST_RETURN gchar *gdk_x11_get_xatom_name_for_display (GdkDisplay *display,
Atom xatom);
#ifndef GDK_MULTIHEAD_SAFE
Atom gdk_x11_atom_to_xatom (GdkAtom atom);
GdkAtom gdk_x11_xatom_to_atom (Atom xatom);
Atom gdk_x11_get_xatom_by_name (const gchar *atom_name);
G_CONST_RETURN gchar *gdk_x11_get_xatom_name (Atom xatom);
#endif
