Karine Delvare 5a9f83bd46 app/tools/gimprectangletool.[ch] transform into an interface. 
2005-08-15  Karine Delvare  <kdelvare@nerim.net>

        * app/tools/gimprectangletool.[ch]
        * app/tools/gimprectangleoptions.[ch]: transform into an interface.

        * app/tools/gimpcroptool.[ch]
        * app/tools/gimpnewrectselecttool.[ch]: use the rectangletool interface.

        * app/tools/gimpcropoptions.[ch]
        * app/tools/gimpnewrectselectoptions.[ch]: use the rectangleoptions
        interface.

        * app/tools/Makefile.am: added gimpnewrectselectionoptions.[ch]
