class GDK_WINDOW
	-- A GdkWindow is a rectangular region on the screen. It's a low-level
	-- object, used to implement high-level objects such as GtkWidget and
	-- GtkWindow on the GTK+ level. A GtkWindow is a toplevel window, the thing
	-- a user might think of as a "window" with a titlebar and so on; a
	-- GtkWindow may contain many GdkWindow. For example, each GtkButton has a
	-- GdkWindow associated with it.

Also, the presence/absence of GDK_HINT_POS, GDK_HINT_USER_POS, and GDK_HINT_USER_SIZE is significant, though they don't directly refer to GdkGeometry fields. GDK_HINT_USER_POS will be set automatically by GtkWindow if you call gtk_window_move(). GDK_HINT_USER_POS and GDK_HINT_USER_SIZE should be set if the user specified a size/position using a --geometry command-line argument; gtk_window_parse_geometry() automatically sets these flags.

	--   GdkGravity win_gravity;

	-- The GdkGeometry struct gives the window manager information about a window's geometry constraints. Normally you would set these on the GTK+ level using gtk_window_set_geometry_hints(). GtkWindow then sets the hints on the GdkWindow it creates.

	-- gdk_window_set_geometry_hints() expects the hints to be fully valid already and simply passes them to the window manager; in contrast, gtk_window_set_geometry_hints() performs some interpretation. For example, GtkWindow will apply the hints to the geometry widget instead of the toplevel window, if you set a geometry widget. Also, the min_width/min_height/max_width/max_height fields may be set to -1, and GtkWindow will substitute the size request of the window or geometry widget. If the minimum size hint is not provided, GtkWindow will use its requisition as the minimum size. If the minimum size is provided and a geometry widget is set, GtkWindow will take the minimum size as the minimum size of the geometry widget rather than the entire window. The base size is treated similarly.

	-- The canonical use-case for gtk_window_set_geometry_hints() is to get a terminal widget to resize properly. Here, the terminal text area should be the geometry widget; GtkWindow will then automatically set the base size to the size of other widgets in the terminal window, such as the menubar and scrollbar. Then, the width_inc and height_inc fields should be set to the size of one character in the terminal. Finally, the base size should be set to the size of one character. The net effect is that the minimum size of the terminal will have a 1x1 character terminal area, and only terminal sizes on the "character grid" will be allowed.

	-- Here's an example of how the terminal example would be implemented, assuming a terminal area widget called "terminal" and a toplevel window "toplevel":

	-- 	GdkGeometry hints;

	-- 	hints.base_width = terminal->char_width;
	--         hints.base_height = terminal->char_height;
	--         hints.min_width = terminal->char_width;
	--         hints.min_height = terminal->char_height;
	--         hints.width_inc = terminal->char_width;
	--         hints.height_inc = terminal->char_height;

	-- 	gtk_window_set_geometry_hints (GTK_WINDOW (toplevel),
	-- 				       GTK_WIDGET (terminal),
	--  				       &hints,
	-- 				       GDK_HINT_RESIZE_INC |
	--                                        GDK_HINT_MIN_SIZE |
	--                                        GDK_HINT_BASE_SIZE);

	-- The other useful fields are the min_aspect and max_aspect fields; these contain a width/height ratio as a floating point number. If a geometry widget is set, the aspect applies to the geometry widget rather than the entire window. The most common use of these hints is probably to set min_aspect and max_aspect to the same value, thus forcing the window to keep a constant aspect ratio.

Only the part of window contained in region will be modified; that is, drawing operations are clipped to region.

	-- The net result of all this is to remove flicker, because the user sees the finished product appear all at once when you call gdk_window_end_paint(). If you draw to window directly without calling gdk_window_begin_paint_region(), the user may see flicker as individual drawing operations are performed in sequence. The clipping and background-initializing features of gdk_window_begin_paint_region() are conveniences for the programmer, so you can avoid doing that work yourself.

	-- When using GTK+, the widget system automatically places calls to gdk_window_begin_paint_region() and gdk_window_end_paint() around emissions of the expose_event signal. That is, if you're writing an expose event handler, you can assume that the exposed area in GdkEventExpose has already been cleared to the window background, is already set as the clip region, and already has a backing store. Therefore in most cases, application code need not call gdk_window_begin_paint_region(). (You can disable the automatic calls around expose events on a widget-by-widget basis by calling gtk_widget_set_double_buffered().)

	-- If you call this function multiple times before calling the matching gdk_window_end_paint(), the backing stores are pushed onto a stack. gdk_window_end_paint() copies the topmost backing store onscreen, subtracts the topmost region from all other regions in the stack, and pops the stack. All drawing operations affect only the topmost backing store in the stack. One matching call to gdk_window_end_paint() is required for each call to gdk_window_begin_paint_region().

	-- window : 	a GdkWindow
	-- region : 	region you intend to draw to
	-- gdk_window_end_paint ()

	-- void        gdk_window_end_paint            (GdkWindow *window);

	-- Indicates that the backing store created by the most recent call to gdk_window_begin_paint_region() should be copied onscreen and deleted, leaving the next-most-recent backing store or no backing store at all as the active paint region. See gdk_window_begin_paint_region() for full details. It is an error to call this function without a matching gdk_window_begin_paint_region() first.

	-- window : 	a GdkWindow

	-- A convenience wrapper around gdk_window_invalidate_region() which invalidates a rectangular region. See gdk_window_invalidate_region() for details.

	--                                              gboolean invalidate_children);

	-- Adds region to the update area for window. The update area is the region that needs to be redrawn, or "dirty region." The call gdk_window_process_updates() sends one or more expose events to the window, which together cover the entire update area. An application would normally redraw the contents of window in response to those expose events.

	-- GDK will call gdk_window_process_all_updates() on your behalf whenever your program returns to the main loop and becomes idle, so normally there's no need to do that manually, you just need to invalidate regions that you know should be redrawn.

	-- The invalidate_children parameter controls whether the region of each child window that intersects region will also be invalidated. If FALSE, then the update area for child windows will remain unaffected. See gdk_window_invalidate_maybe_recurse if you need fine grained control over which children are invalidated.

	-- Adds region to the update area for window. The update area is the region that needs to be redrawn, or "dirty region."

	-- The child_func parameter controls whether the region of each child window that intersects region will also be invalidated. Only children for which child_func returns TRUE will have the area invalidated.

	-- window : 	a GdkWindow
	-- region : 	a GdkRegion
	-- child_func : 	function to use to decide if to recurse to a child, NULL means never recurse.

	-- gdk_window_get_update_area ()

	-- GdkRegion*  gdk_window_get_update_area      (GdkWindow *window);

	-- Transfers ownership of the update area from window to the caller of the function. That is, after calling this function, window will no longer have an invalid/dirty region; the update area is removed from window and handed to you. If a window has no update area, gdk_window_get_update_area() returns NULL. You are responsible for calling gdk_region_destroy() on the returned region if it's non-NULL.

	-- window : 	a GdkWindow
	-- Returns : 	the update area for window
	-- gdk_window_freeze_updates ()

	-- void        gdk_window_freeze_updates       (GdkWindow *window);

	-- Temporarily freezes a window such that it won't receive expose events. The window will begin receiving expose events again when gdk_window_thaw_updates() is called. If gdk_window_freeze_updates() has been called more than once, gdk_window_thaw_updates() must be called an equal number of times to begin processing exposes.

	-- window : 	a GdkWindow
	-- gdk_window_thaw_updates ()

	-- void        gdk_window_thaw_updates         (GdkWindow *window);

	-- Thaws a window frozen with gdk_window_freeze_updates().

	-- window : 	a GdkWindow
	-- gdk_window_process_all_updates ()

	-- void        gdk_window_process_all_updates  (void);

	-- Calls gdk_window_process_updates() for all windows (see GdkWindow) in the application.

	-- gdk_window_process_updates ()

	-- void        gdk_window_process_updates      (GdkWindow *window,
	--                                              gboolean update_children);

	-- Sends one or more expose events to window. The areas in each expose event will cover the entire update area for the window (see gdk_window_invalidate_region() for details). Normally GDK calls gdk_window_process_all_updates() on your behalf, so there's no need to call this function unless you want to force expose events to be delivered immediately and synchronously (vs. the usual case, where GDK delivers them in an idle handler). Occasionally this is useful to produce nicer scrolling behavior, for example.

	-- window : 	a GdkWindow
	-- update_children : 	whether to also process updates for child windows
	-- gdk_window_set_debug_updates ()

	-- void        gdk_window_set_debug_updates    (gboolean setting);

	-- With update debugging enabled, calls to gdk_window_invalidate_region() clear the invalidated region of the screen to a noticeable color, and GDK pauses for a short time before sending exposes to windows during gdk_window_process_updates(). The net effect is that you can see the invalid region for each window and watch redraws as they occur. This allows you to diagnose inefficiencies in your application.

	-- In essence, because the GDK rendering model prevents all flicker, if you are redrawing the same region 400 times you may never notice, aside from noticing a speed problem. Enabling update debugging causes GTK to flicker slowly and noticeably, so you can see exactly what's being redrawn when, in what order.

	-- The --gtk-debug=updates command line option passed to GTK+ programs enables this debug option at application startup time. That's usually more useful than calling gdk_window_set_debug_updat…
