Fix #882 has created new problem

[refdoc]

As result of #882 the crashes are now avoided but both the scroll down menu for book names and the chapter choser are misplaced

(Debian stretch)

[karlkleinpaste]

the entirety of the change for #882 is to replace "0,0" pairs in menu popups with GDK gravity indicators, e.g.:

-               gtk_menu_popup_at_widget(GTK_MENU(menu), widget, 0, 0, NULL);
+               gtk_menu_popup_at_widget(GTK_MENU(menu), widget, GDK_GRAVITY_SOUTH_WEST, GDK_GRAVITY_NORTH_WEST, NULL);

how can this possibly have had the slightest effect on chooser placement? are we looking at an actual xiphos problem, or instead a GTK or Wayland problem?

i hate the github editor. i hate it, hate it, hate it.
those 2 lines were the '-'/'+' lines of "git diff" of one example use of gtk_menu_popup_at_widget.

@karlkleinpaste I've updated your comment to properly show and highlight that as a patch diff.

Ok some more info re what is happening:

The three drop down menus (book name, chapter no, verse no) will, if too long move to the left edge of the Xiphos window. So, if a chapter e.g. has only 10 verses the drop down menu will be in the usual and normal place. If a book has only 10 chapters, same. But if a book has a lot of chapters or a chapter lots of verses then the menu will detach and hang on the edge of Xiphos' window.

The terminal printout is
(xiphos:2283): Gdk-CRITICAL **: 20:39:58.002: gdk_window_get_window_type: assertion 'GDK_IS_WINDOW (window)' failed

I think what is happening is that this particular set of menus are a bit cobbled together and are not using standard menu widgets. And this worked so far, but is now causing grief.

From one of the files a commentary:
