Fix handling of the geometry widget The geometry widget feature of gtk_window_set_geometry_hints() has never really worked right because the calculation that GTK+ did to compute the base size of the window only worked when the geometry widget had a larger minimum size than anything else in the window. Setup: * Move the GtkSizeGroup private functions to a new private header gtksizegroup-private.h * Add the possibilty to pass flags to _gtk_size_group_queue_resize(), with the flag GTK_QUEUE_RESIZE_INVALIDATE_ONLY to suppress adding the widget's toplevel to the resize queue. * _gtk_container_resize_invalidate() is added to implement that feature * _gtk_widget_override_size_request()/_gtk_widget_restore_size_request() allow temporarily forcing a large minimum size on the geometry widget without creating resize loops. GtkWindow: * Compute the extra width/height around the geometry widget correctly; print a warning if the computation fails. * Always make the minimum size at least the natural minimum size of the toplevel; GTK+ now fails badly with underallocation. * Always set the base size hint; we were failing to set it properly when the specified minimum size was overriden, but it's harmless to always set it. Tests: * New test 'testgeometry' that replaces the 'gridded geometry' test from testgtk. The new test is roughly similar but creates a bunch of windows showing different possibilities. * The testgtk test is removed. No need to have both. https://bugzilla.gnome.org/show_bug.cgi?id=68668
