Extra White Space with right aligned Fonts
Some symbologies require a "quiet area" separating the final bar
of the barcode and the next symbol, character, or image encountered.
This "quiet area" is necessary to allow the scanner to process the barcode
without interference from adjacent objects.
To ensure that IDAutomation fonts meet the requirements of certain
symbologies, this "quiet area" is built into the font as a white space
after the last bar of the stop character for the symbology.
