The idea is that a layout flush should only do layout until the part we
care about is stable. Or something.
Could we do the particular optimization that Chrome is doing in Servo by
just threading "what part of layout are we interested in?" (the
LayoutGoal in Servo terms) throughout layout and sending the answer over
a channel as soon as we know it?
For example, if we want offsetWidth of a div, then we could make the
LayoutGoal something like "offsetWidth of div so-and-so" and then as
soon as we know the answer send it to the content task. We would
continue doing the layout as usual in the layout thread.
