set_use_layout_size
Description:
Changes the way this requests size.
 If use_layout_size is true, the this widget will request the size that the
      LayoutManager reports as the preferred size. This means that a Gtk+ window will automatically get the natural and minimum toplevel window sizes.
      This is useful when the contents of the clutter stage is similar to a traditional UI.
If use_layout_size is false (which is the default) then this will not request any
      size and its up to the embedder to make sure there is some size (by setting a custom size on the widget or a default size on the toplevel. This
      makes more sense when using the this as a viewport into a potentially unlimited clutter space.
Parameters:
| this | a Embed | 
| use_layout_size | a boolean |
