/*
 * These macros are used for debugging purposes. They expand
 * to white spaces on a free build. Here is a brief description
 * of what they do and how they are used:
 *
 * giDebugLevel
 *  Global variable which set the current debug level to control
 *  the amount of debug messages emitted.
 *
 * VERBOSE(msg)
 *  Display a message if the current debug level is <= DBG_VERBOSE.
 *
 * TERSE(msg)
 *  Display a message if the current debug level is <= DBG_TERSE.
 *
 * WARNING(msg)
 *  Display a message if the current debug level is <= DBG_WARNING.
 *
 * ERR(msg)
 *  Similiar to WARNING macro above - displays a message
 *  if the current debug level is <= DBG_ERROR.
 *
 * Usage:
 *  These macros require extra parantheses for the msg argument
 *  example, WARNING(("App passed NULL pointer, ignoring...\n"));
