// This file allows easier debugging of Mac OS X Core Graphics 
// code. This file is normally not included into any FLTK builds,
// but since it has proven to be tremendously useful in debugging
// the FLTK port to "Quartz", I decided to add this file in case
// more bugs show up.
//
// This header is activated by adding the following
// line to "config.h"
//   #include "src/cgdebug.h"
//
// Running "./configure" will remove this line from "config.h".
//
// When used erreanously, Core Graphics prints warnings to 
// stderr. This is helpful, however it is not possible to 
// associate a line number or source file with the warning message.
// This headr file outputs a trace of CG calls, interweaveing
// them with CG warnings.
