 When the logger encounters a %x in the format string, it will call the processor (if it isn't NULL) with
-user_data as the first argument, an index as the second, and the log level as the third.  The index is a 0-up
-counter of which %x in the format string is being handled.  The fourth and fifth arguments will be pointers
-to the destination and remaining size and function as in vasqIncSnprintf.  The processor is responsible for
-adjusting these two values (recall that the terminator is not included in the calculation).  The processor
-can write a terminator at the end but it is not necessary.
