* When the precision specifier is an integer value, it reduces the size of the logger name.
If the number is positive, the layout prints the corresponding number of the rightmost logger name components.
If negative, the layout removes the corresponding number of leftmost logger name components.
* If the precision contains periods then the number before the first period identifies the length to be printed from items that precede tokens in the rest of the pattern.
If the number after the first period is followed by an asterisk it indicates how many of the rightmost tokens will be printed in full.
* If the precision contains periods then the number before the period identifies the length to be printed from items that precede the matching period in the logger name.
An asterisk can be used as a wildcard to print the whole logger name component before a period.
* If the precision contains any non-integer characters, then the layout abbreviates the name based on the pattern.
If the precision integer is less than one, the layout still prints the right-most token in full.
