hooper 2300a76a07 Add size restrictions for some barcode types
No longer allows symbols of size less than 2mm high or 2mm wide
Enforces correct sizing for Australia Post, Intelligent Mail, Royal Mail 4-State and KIX Code
Adjusts ascender/tracker/descender proportions on all 4-state codes to revised 3/2/3 standards
Enforces normative sizing for UPC and EAN
Enforces minimum sizing for Codabar and Code 49
Tidies up the code a bit so that all of the above makes some sense
