Changes to update terminology

We are expressing font-sizes in pixels today. However, for our definition
of large scale print we use

large scale (text)

with at least 18 point or 14 point bold or font size that would yield
equivalent size for Chinese, Japanese and Korean (CJK) fonts



This is with referenced in 1.4.3 and 1.4.6.


Shouldn't we change this to 18pt to 24px and  14pt to (18 or 19px)
depending on whether we want to round up of truncate the fraction.
