3749  * The #GdkGeometry struct gives the window manager information about
3750  * a window’s geometry constraints. Normally you would set these on
3751  * the GTK+ level using gtk_window_set_geometry_hints(). #GtkWindow
3752  * then sets the hints on the #GdkWindow it creates.
3753  *
3754  * gdk_window_set_geometry_hints() expects the hints to be fully valid already
3755  * and simply passes them to the window manager; in contrast,
3756  * gtk_window_set_geometry_hints() performs some interpretation. For example,
3757  * #GtkWindow will apply the hints to the geometry widget instead of the
3758  * toplevel window, if you set a geometry widget. Also, the
3759  * @min_width/@min_height/@max_width/@max_height fields may be set to -1, and
3760  * #GtkWindow will substitute the size request of the window or geometry widget.
3761  * If the minimum size hint is not provided, #GtkWindow will use its requisition
3762  * as the minimum size. If the minimum size is provided and a geometry widget is
3763  * set, #GtkWindow will take the minimum size as the minimum size of the
3764  * geometry widget rather than the entire window. The base size is treated
3765  * similarly.
3766  *
3767  * The canonical use-case for gtk_window_set_geometry_hints() is to get a
3768  * terminal widget to resize properly. Here, the terminal text area should be
3769  * the geometry widget; #GtkWindow will then automatically set the base size to
3770  * the size of other widgets in the terminal window, such as the menubar and
3771  * scrollbar. Then, the @width_inc and @height_inc fields should be set to the
3772  * size of one character in the terminal. Finally, the base size should be set
3773  * to the size of one character. The net effect is that the minimum size of the
3774  * terminal will have a 1x1 character terminal area, and only terminal sizes on
3775  * the “character grid” will be allowed.
3776  *
3777  * Here’s an example of how the terminal example would be implemented, assuming
3778  * a terminal area widget called “terminal” and a toplevel window “toplevel”:
3779  *
3780  * |[<!-- language="C" -->
3781  * GdkGeometry hints;
3782  *
3783  * hints.base_width = terminal->char_width;
3784  * hints.base_height = terminal->char_height;
3785  * hints.min_width = terminal->char_width;
3786  * hints.min_height = terminal->char_height;
3787  * hints.width_inc = terminal->char_width;
3788  * hints.height_inc = terminal->char_height;
3789  *
3790  * gtk_window_set_geometry_hints (GTK_WINDOW (toplevel),
3791  * GTK_WIDGET (terminal),
3792  * &hints,
3793  * GDK_HINT_RESIZE_INC |
3794  * GDK_HINT_MIN_SIZE |
3795  * GDK_HINT_BASE_SIZE);
3796  * ]|
3797  *
3798  * The other useful fields are the @min_aspect and @max_aspect fields; these
3799  * contain a width/height ratio as a floating point number. If a geometry widget
3800  * is set, the aspect applies to the geometry widget rather than the entire
3801  * window. The most common use of these hints is probably to set @min_aspect and
3802  * @max_aspect to the same value, thus forcing the window to keep a constant
3803  * aspect ratio.
