	  Move port-independent singlehead wrapper functions into

	  gdk/win32/gdkselection-win32.c gdk/win32/gkwindow-win32.c:
	Turn singlehead functions into "multihead" functions that ignore
	their GdkDisplay or GdkScreen arguments.

	* gdk/win32/gdkdrawable-win32.c gdk/win32/gdkevents-win32.c
	gdk/win32/gdkinput-win32.c gdk/win32/gdkprivate-win32.h:
	Misc multihead-compatibility changes.

	* gtk/gtk.def gdk/gdk.def: Update for multihead functions.

	  gdk/x11/gdkimage-x11.c gdk/x11/gdkprivate-x11.h gtk/gtkgc.c
	  gtk/gtkstyle.c gtk/gtkwidget.c: Use accessors to get the screen
	for colormaps, visuals; move the fields into the private
	structures for the x11 backend.

	* gdk/gdkdisplay.[ch] gdk/x11/gdkdisplay-x11.[ch]
	  gdk/gdkscreen.[ch] gdk/x11/gdkscreen-x11.c:
	Remove virtualization of screen and display functions.
	(#79990, patch from Erwann Chenede)

	* gdk/win32/gdkdisplay-x11.c gdk/win32/gdkscreen-win32.c
	gdk/win32/{Makefile.am, makefile.msc, makefile.mingw}:
	New files containing stub implementations of Display,
	Screen functions.

	* gdk/x11/gdkscreen-x11.[ch] gdk/x11/gdkdisplay-x11.[ch]
	gdk/x11/gdkx.h: Clean up function exports and what
	headers they are in. (#79954)

	* gdk/x11/gdkx.h: Fix macro that was referring to a non-existant
	screen->screen_num. (In the patch for #79972, Erwann Chenede)

	* gdk/gdkscreen.c gdk/gdkwindow.c gdk/x11/gdkinternals.h
	 gdk/x11/gdkscreen-x11.c: Fix gdk_screen_get_window_at_pointer()
	to use window hooks. (#79972, patch partly from Erwann Chenede)
