Take transform:translate into account when computing clipping regions.
Note that this only works for translation; a more general fix would
require major changes to how display lists work.
Closes#10431?

Improve PerformanceTiming Interface
Solving https://github.com/servo/servo/issues/10428
- Fix timing precision in old `update_with_current_time`
- Correct time unit in `navigation_start`
- Add `LoadEventStart` and `LoadEventEnd` timing properties
There are still many properties left unimplemented. I tend to leave the for future PRs.
Welcome comments!

gfx: Clamp the font size we supply to Core Text to 0.01pt.
Core Text treats a font size of 0.0 as 12.0, which is obviously not what
we want.

layout: Allow non-absolutely-positioned elements with `overflow: scroll` set to be scrolled.
This makes them establish stacking contexts, which is a CSS 2.1 spec
violation. However, we were already violating the spec here for
absolutely-positioned elements with `overflow: scroll`. It will probably
be easier to fix this spec violation once we either switch entirely to
WebRender or we have multiple layers per stacking context.
