17// This file allows easier debugging of Mac OS X Core Graphics
18// code. This file is normally not included into any FLTK builds,
19// but since it has proven to be tremendously useful in debugging
20// the FLTK port to "Quartz", I decided to add this file in case
21// more bugs show up.
22//
23// This header is activated by adding the following
24// line to "config.h"
25// #include "src/cgdebug.h"
26//
27// Running "./configure" will remove this line from "config.h".
28//
29// When used erreanously, Core Graphics prints warnings to
30// stderr. This is helpful, however it is not possible to
31// associate a line number or source file with the warning message.
32// This headr file outputs a trace of CG calls, interweaveing
33// them with CG warnings.
