Callbacks in the CSS will hopefully eventually disappear once we make
the CSS truly static.  A list of additional CSS files to include won't.

There are also large caveats regarding CSS squishing if you use any of
the "Begin" callbacks in CSS.  This is why "End" callbacks should always
be used.

CSS injected by the callbacks is indeed minified.  That the doc suggests
otherwise (although doesn't explicitly claim callbacks aren't minified)
is wrong.  Send a small doc patch?
