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