    Fix handling of the geometry widget · 88cf5470
    Owen W. Taylor authored
    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.
