[plt-scheme] MrEd: container-size with border style

If I make a panel% with a 'border style, and I'm overriding the
container-size method, should it include the size of the border as
well?  That appears to be the case, because place-children is being
called with a smaller size than container-size is returning.

How do I figure out what the size of the border is?  (The border
method seems to be independent of the 'border style.)  How can I even
tell if a panel% has a border (other than intercepting the style
instantiation argument)?
