Finds or creates an atom corresponding to a given string.
Note that this function is identical to gdk_atom_intern() except
that if a new #GdkAtom is created the string itself is used rather
than a copy. This saves memory, but can only be used if the string
will always exist. It can be used with statically
allocated strings in the main program, but not with statically
allocated memory in dynamically loaded modules, if you expect to
ever unload the module again (e.g. do not use this function in
GTK+ theme engines).
