I gave a local TOC for convenience. Also starred sections have been changed.
The first section is altered quite a bit. However most of the changes are  
to include the new disability group, people with limited visual field. This  
required a rearrangement of many paragraphs. No substantive change was  
intended.

The section on 1.4.4 is reworked. With an example of how authors can  
prevent zoom to 200%.

Example 2 was added to show when shrinking text is OK.

I changed the reference from my web page to the official refereed  
publication.

Thats all,

Wayne
