	* gdk/win32/gdkwindow-win32.c: Remove unnecessary includes.

	(_gdk_win32_get_adjusted_client_rect): Remove this two-line
	function which was used only in one place.

	(get_outer_rect): Use _gdk_win32_adjust_client_rect().

	(gdk_window_set_geometry_hints): If we have identical minimum and
	maximum size hints, remove the resize and maximize
	decorations/functions. (#104514)

	If we have a maximum size hint, remove the maximize
	decoration/function but ensure the resize decoration/function is
	available. Otherwise ensure both resize and maximize
	decorations/functions are there.

	(set_or_clear_style_bits): Factored out common code from
	gdk_window_set_decorations() and gdk_window_set_functions().

	Hack the window style setting once more: Only touch the window
	style bits corresponding to the GdkWMDecoration or GdkWMFunction
	parameter bitmasks. Hopefully this finally is the correct thing to
	do. We used to clear all other bits than those that were being
	set, or set all other bits than those that were being cleared.

	Take into account that adding or removing decorations leaves the
	window's outer size unchanged, i.e., the client area's size and
	position change. This is apparently not what we want, so change
	also the window's (outer) position and size appropriately so that
	the client area's position and size stay constant.

	gtk-demo's color selector dialog is now non-resizable like on X11
	(I tested with metacity in GNOME). Torn off menus are shrinkable
	vertically but have a maximum size, and are not maximizable or
	minimizable, like on X11.

	(gdk_window_set_decorations, gdk_window_set_functions): Let
	set_or_clear_decorations() do most of the job.

	* gdk/win32/gdkprivate-win32.h: Remove declaration of
	_gdk_win32_get_adjusted_client_rect().
