-/* Define PNG_DEBUG at compile time for debugging information.  Higher

- * numbers for PNG_DEBUG mean more debugging information.  This has

- * only been added since version 0.95 so it is not implemented throughout

- * libpng yet, but more support will be added as needed.

- *

- * png_debug[1-2]?(level, message ,arg{0-2})

- *   Expands to a statement (either a simple expression or a compound

- *   do..while(0) statement) that outputs a message with parameter

- *   substitution if PNG_DEBUG is defined to 2 or more.  If PNG_DEBUG

- *   is undefined, 0 or 1 every png_debug expands to a simple expression

- *   (actually ((void)0)).

- *

- *   level: level of detail of message, starting at 0.  A level 'n'

- *          message is preceded by 'n' tab characters (not implemented

- *          on Microsoft compilers unless PNG_DEBUG_FILE is also

- *          defined, to allow debug DLL compilation with no standard IO).

- *   message: a printf(3) style text string.  A trailing '\n' is added

- *            to the message.

- *   arg: 0 to 2 arguments for printf(3) style substitution in message.
