Matthias Clasen 929a56e53c Clean up lots of GTK+ -> GTK 
Replace most remaining uses of GTK+ in the docs and
user-visible strings by GTK. Also remove some leftover
"Was added in 3.x" sentences from the docs.

/**
* SECTION:gtkwindow
* @title: GtkWindow
* @short_description: Toplevel which can contain other widgets
*
* A GtkWindow is a toplevel window which can contain other widgets.
* Windows normally have decorations that are under the control
* of the windowing system and allow the user to manipulate the window
* (resize it, move it, close it,...).
*
* # GtkWindow as GtkBuildable
*
* The GtkWindow implementation of the #GtkBuildable interface supports
* setting a child as the titlebar by specifying “titlebar” as the “type”
* attribute of a <child> element.
*
* # CSS nodes
*
* |[<!-- language="plain" -->
* window.background
* ├── <child>
* ╰── <titlebar child>.titlebar [.default-decoration]
* ]|
*
* GtkWindow has a main CSS node with name window and style class .background.
*
* Style classes that are typically used with the main CSS node are .csd (when
* client-side decorations are in use), .solid-csd (for client-side decorations
* without invisible borders), .ssd (used by mutter when rendering server-side
* decorations). GtkWindow also represents window states with the following
* style classes on the main node: .tiled, .maximized, .fullscreen. Specialized
* types of window often add their own discriminating style classes, such as
* .popup or .tooltip.
*
* Generally, some CSS properties don't make sense on the toplevel window node,
* such as margins or padding. When client-side decorations without invisible
* borders are in use (i.e. the .solid-csd style class is added to the
* main window node), the CSS border of the toplevel window is used for
* resize drags. In the .csd case, the shadow area outside of the window
* can be used to resize it.
*
* GtkWindow adds the .titlebar and .default-decoration style classes to the
* widget that is added as a titlebar child.
*
* # Accessibility
*
* GtkWindow uses the #GTK_ACCESSIBLE_ROLE_WINDOW role.

* a widget and thus would keep users from shrinking the window, this
* function only sets the initial size, just as if the user had
* resized the window themselves. Users can still shrink the window
* again as they normally would. Setting a default size of -1 means to
* use the “natural” default size (the size request of the window).
*
* For some uses, gtk_window_resize() is a more appropriate function.
* gtk_window_resize() changes the current size of the window, rather
* than the size to be used on initial display. gtk_window_resize() always
* affects the window itself, not the geometry widget.
*
* The default size of a window only affects the first time a window is
* shown; if a window is hidden and re-shown, it will remember the size
* it had prior to hiding, rather than using the default size.
*
* Windows can’t actually be 0x0 in size, they must be at least 1x1, but
* passing 0 for @width and @height is OK, resulting in a 1x1 default size.
*
* If you use this function to reestablish a previously saved window size,
* note that the appropriate size to save is the one returned by
* gtk_window_get_size(). Using the window allocation directly will not
* work in all circumstances and can lead to growing or shrinking windows.

* not be smaller than their size request; to override this
* constraint, call gtk_widget_set_size_request() to set the window's
* request to a smaller value.
*
* If gtk_window_resize() is called before showing a window for the
* first time, it overrides any default size set with
* gtk_window_set_default_size().
*
* Windows may not be resized smaller than 1 by 1 pixels.
*
* When using client side decorations, GTK will do its best to adjust
* the given size so that the resulting window size matches the
* requested size without the title bar, borders and shadows added for
* the client side decorations, but there is no guarantee that the
* result will be totally accurate because these widgets added for
* client side decorations depend on the theme and may not be realized
* or visible at the time gtk_window_resize() is issued.
*
* If the GtkWindow has a titlebar widget (see gtk_window_set_titlebar()), then
* typically, gtk_window_resize() will compensate for the height of the titlebar
* widget only if the height is known when the resulting GtkWindow configuration
* is issued.
* For example, if new widgets are added after the GtkWindow configuration
* and cause the titlebar widget to grow in height, this will result in a
* window content smaller that specified by gtk_window_resize() and not
* a larger window.

* configure_request_pos_changed = TRUE. configure_request_size_changed

* or gtk_window_move().
*
* If the configure request has changed, we send off a new one. To
* ensure GTK invariants are maintained (resize queue does what it
* should), we go ahead and size_allocate the requested size in this
* function.
*
* If the configure request has not changed, we don't ever resend
* it, because it could mean fighting the user or window manager.
*
* To prepare the configure request, we come up with a base size/pos:
* - the one from gtk_window_move()/gtk_window_resize()
* - else default_width, default_height if we haven't ever
* been mapped
* - else the size request if we haven't ever been mapped,
* as a substitute default size
* - else the current size of the window, as received from
* configure notifies (i.e. the current allocation)
