/* 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' 3-space indentations (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.
