* border_width attribute should be removed?
* Some of the code needs to be reformatted to conform to gtk's indentation and 
  brace placement
* needs to support the re-configurability a gtkbox (as of recently) offers one 
  through the 
  gtk_box_query_child_packing/gtk_box_reorder_child/gtk_box_set_child_packing
  interface (i know part of this is already done by the gtk_packer_configure
  function). this is neccessary for an interface builder (especially to change
  the use_default flag per widget).
* Widget arguments need to be implemented
