+/* pngdebug.h - Debugging macros for libpng, also used in pngtest.c

+ * Copyright (c) 1998-2002,2004,2006-2013 Glenn Randers-Pehrson

+/* 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.
