When absolute positioning is used, something like top:auto creates a strange
gap that I don't understand.  It's probably OK by the spec (because the spec is
necessarily vague for other reasons), but that doesn't mean it should be there.
See the <P class="nine"> in the above URL and also, in
http://www.fas.harvard.edu/~dbaron/csstest/sec090302c.html , examples of class
nine, nineb, and nined (and currently more because bottom isn't working).

It also occurs on the left side in the P class="nine" in
http://www.fas.harvard.edu/~dbaron/csstest/sec090302b.html

This is fixed now. That strange gap was because when the 'placeholder' frame's
position was being translated back into the coordinate space of the containing
block it was left relative to the containing block's border edge instead of the
containing block's padding edge like it should be. So I added some code to
translate by the containing block's 'border'
