[gimp/metadata-browser] app: remove drawable->private->format, its buffer has a format already



commit bc420db3b8d4dedf18e85b7774aa6bf78235a945
Author: Michael Natterer <mitch gimp org>
Date:   Thu Mar 29 23:19:27 2012 +0200

    app: remove drawable->private->format, its buffer has a format already
    
    Also, make group layer type conversion much less hackish by using the
    same kind of temporary states that are used for reallocating its
    projection on size change.
