Size of 2.19.19 notation PDF

[Nick Payne]

I notice that the notation.pdf that I downloaded for 2.19.19 is about 
half the size of its predecessors - 17.2Mb vs 30.8Mb for the 2.19.18 
notation manual. I downloaded it twice to verify and got the same size 
each time. On a quick check of the file I didn't find anything obviously 
missing.

All the other manuals as PDFs are much the same size as previously with 
the exception of the snippets manual, which is about 75% of it's 
previous size.
