To be multihead safe, each new window or menu needs to be associated with

	To be multihead safe, each new window or menu needs to be
	associated with a GdkScreen or it will pop up on the default
	screen.

	* app/gui/vectors-commands.[ch]: added "GtkWidget *parent"
	paramaters to all functions which create menus, popups or windows
	and pass "parent" to gimp_dialog_new() or one of the various
	wrappers around it. As a side effect, this fixes bug #61092.

	* app/widgets/gimpdialogfactory.[ch]: added "GdkScreen *screen"
	instead of "parent" here since there are no possible parent
	windows on startup.

	* app/display/gimpdisplayshell-callbacks.c
	(gimp_display_shell_origin_button_press): added a quick hack to
	send a display to another screen: click the origin button with the
	middle mouse button.

	* app/display/gimpdisplayshell.c
	(gimp_display_shell_screen_changed): don't chain up
	undonditionally (don't crash).

	* libgimpwidgets/gimpdialog.c (gimp_dialog_new_valist): set the
	dialog's screen from a non-GtkWidget parent widget. The rest of
	non-window parent widget handling is still unimplemented.
