Handler.Box displays an incorrectly sized box

Should we cache the border size, instead of re-fetching it every time we change the box size? I think the likelihood that a cached value would change while the box was being drawn to be unlikely enough that it might be worth the performance gain to just always cache it... Or should we not bother?

as suggested with caching, and smarter detection if something needs to be done or not (by detection of standards compliant mode)

Comments:

Line 184:

var dims = OpenLayers.Element.getDimensions(this.zoomBox);

Unused dims var? can we drop this?

Can we expand the comment on:

        // depending on the box model, modify width and height to take borders
        // of the box into account

Can we mention explicitly that newBoxModel is for "IE in non-compat mode" or whatever it actually is, to explain why we have to futz with it?

additional comment, removed unused variable
