Gets the size request that was explicitly set for the widget using set_size_request.
A value of -1 stored in width or height indicates that that dimension has not been set explicitly and the
natural requisition of the widget will be used instead. See set_size_request
. To get the size a widget will actually request, call get_preferred_size
instead of this function.
