Subject: All AFP library classes without Renderer dependencies moved from
 org.apache.fop.renderer.afp.* to org.apache.fop.afp.*. AbstractNamedAFPObject
 now truncates names to the last x characters of the name string instead of
 the first x (where x is the name length of the structured field). Removed
 redundant package org.apache.fop.store.
