Summary of Issue: 1.4.4 - 200% is too high
Comment (Including rationale for any proposed change):
soon all common modern browsers will provide a zoom function.



200% of 12pt - 16px - 1em is 32px. not many layouts online will stand 200% text resizing.



the most common browser internet explorer does not even allow text resizing of 200%, as far as i know the two possible steps resize to 150%??

Proposed Change:
allow text resizing for at least two text resizing steps of common browsers
