Text Size

I am proposing the following minor change (on the wiki) to the wording of
this SC as follows:
Except for images of text, and @@captions with time-based media@@, text can
be resized to @@the user agent maximum without loss of content and
functionality.@@

I was worried about captions because there is a table caption element and a
figcaption element. Where would these fit? So, I reintroduced captions but
made them tied to time-based media. That is unambiguous, I think.

Saying an English sentence is unambiguous is a little like asking God to
strike you with lightning.
