Previously, columns_size_request and columns_size_allocate would each loop over all the widgets doing computations for both width and height. Now I've separated out the width parts from the height parts, and moved both out into four new functions, so that the top-level columns_size_request and columns_size_allocate are just wrappers that call the new functions and plumb size and position information between them and GTK. Actual functionality should be unchanged by this patch.
