[csswg-drafts] [cssom-view] layout viewport vs visual viewport

zcorpan has just created a new issue for 
https://github.com/w3c/csswg-drafts:

== [cssom-view] layout viewport vs visual viewport ==
https://github.com/w3c/csswg-drafts/issues/206 is about introducing 
the terms "layout viewport" and "visual viewport"

https://drafts.csswg.org/cssom-view/ should use these terms instead of
 just "viewport".

https://docs.google.com/spreadsheets/d/11DfDDa-s1hePVwBn3PZidlPJZ9ahhkJ44dyuMiOQtrc/edit#gid=0
 looks like a useful starting point.
