Better command-line logging without losing the possibility to fine-tune Commons Logging from outside. Submitted by: Finn Bock <bckfnn.at.apache.org> plus using the new CommandLineLogger for PFMReader and TTFReader, too. git-svn-id: https://svn.apache.org/repos/asf/xmlgraphics/fop/trunk@197940 13f79535-47bb-0310-9956-ffa450edef68tags/Root_Temp_KnuthStylePageBreaking
