/* WARNING! The marco below is a remarkably ugly hack, intended to log the
   call location of the debug calls without having to create the SRC_LOCATION_INFOs every time
   DEBUG_DECORATOR::Something() is called.
 
   Also checks if debug is enabled at all prior to calling decorator methods, thus saving some
   time wasted otherwise for string formatting and copying the geometry. */
