The only reason it was on style_traits is so that they could use it from some
other crates, but Servo eventually ends up getting the value from an integer, so
may as well pass it around and do that in the end of the process anyway.

Reduce unnecessary iframe size messages
This should be an improvement on pages that include iframes, since we currently run two layout jobs for every display-oriented layout request. When building the display list, we send a message to the constellation that includes the sizes of all iframes present, and the constellation sends resize messages to the script thread. This results in a mouse event on the outer page causing all frames to be re-laid out even if no changes occurred to the iframe sizes, which is ridiculous.
