Note: The reftest uses a transition of non-zero duration, because I couldn't find any other way to reproduce the bug. Unfortunately this makes it unreliable in debug builds. I tried to fix this using reftest-wait with setTimeout and requestAnimationFrame, but it still wouldn't complete the animation consistently. To make the test work in debug builds we may need `transitionend` events (#10245) or a different way to reproduce the bug.

The old code tried to do the speculation as a single bottom-up pass
after intrinsic inline-size calculation, which was unable to handle
cases like this:
<div>
<div style="float: left">Foo</div>
</div>
<div>
<div style="overflow: hidden">Bar</div>
</div>
No single bottom-up pass could possibly handle this case, because the
inline-size of the float flowing out of the "Foo" block could never make
it down to the "Bar" block, where it is needed for speculation.
On the pages I tried, this regresses layout performance by 1%-2%.
I first noticed this breaking some pages, like the Google SERPs, several

A few changes:
* Make `compute_damage` short-circuit more, by skipping comparisons if they will only set flags that are already set.
* Update some obsolete comments.
* Add a bunch of missing properties to `compute_damage`.
* Set `RECONSTRUCT_FLOW` when `text-decoration` changes, because it can affect text fragment splitting/merging.
I believe this is all of the computed properties except for the animation properties. (I wasn't sure what to do with those.) After this lands I'd like to work on moving this information into `properties.mako.rs` so that this function can be auto-generated, and so that newly-added properties can default to setting all flags instead of none.

Right now, there's a huge amount of complexity in T{Node,Element,Document} and friends because of the lifetime parameter.
Before I started generalizing this code for use by Gecko, these wrappers were plain structs. They had (and still have) a phantom lifetime associated with them to prevent references to DOM nodes from leaking past the end of restyle, when they might be invalidated by a GC.
When I generalized them, I decided to put the lifetime on the trait as well, since there are some situations where the lifetime is, in fact, necessary. Specifically, they are necessary for the compiler to understand that all the things borrowed from all the nodes and elements and so on have the same lifetime (the lifetime of the restyle), rather than the lifetime of whichever particular element or node pointer the value was borrowed from. This come up in situations where we do |let el = node.as_element()| or |let n = el.as_node()| and then borrow something from the result. The compiler thinks the borrow lifetime is that of |el| or |n|, when it's actually longer.
In practice though, I think the style and layout algorithms we use don't run into this issue much, and we can hack around it where it comes up. So I think we should remove the lifetimes from the traits, which will let us aggregate the embedding-provided traits together onto a single meta-trait and significantly simplify the code.

This fixes#7846, a failure in the "quotes-036.htm" test. Servo lays out this test correctly in its initial layout, but then messes it up in any relayout (whether it's an incremental or full layout).
The problem is that the ResolveGeneratedContent traversal is not safe to run more than once on the same flow. It mutates some GeneratedContent fragments into ScannedText fragments, but leaves others unmodified (in particular, those that generate empty content). The next time layout runs, these remaining GeneratedContent fragments are processed *again* but with an incorrect correct quote nesting level (because some of the surrounding GeneratedContent fragments are gone).
This patch ensures that each GeneratedContent fragment is resolved only once.

Previously, the flow for ticking animations was:
Compositor -> Constellation -> Layout -> Script
However, this means that the compositor <-> layout messages can thrash, meaning layout thread is very rarely idle.
This means that the script thread (which joins on the layout thread during reflow) was unable to execute and run rAF callbacks.
With this change, the flow is now:
Compositor -> Constellation -> Script (when rAF is active).
Compositor -> Constellation -> Layout (when transitions / animations are active and no rAF is present).
This makes rAF based animation *much* smoother.

Instead of producing a tree of stacking contexts, display list
generation now produces a flat list of display items and a tree of
stacking contexts. This will eventually allow display list construction
to produce and modify WebRender vertex buffers directly, removing the
overhead of display list conversion. This change also moves
layerization of the display list to the paint thread, since it isn't
currently useful for WebRender.
To accomplish this, display list generation now takes three passes of
the flow tree:
1. Calculation of absolute positions.
2. Collection of a tree of stacking contexts.
3. Creation of a list of display items.
After collection of display items, they are sorted based upon the index
of their parent stacking contexts and their position in CSS 2.1
Appendeix E stacking order.
This is a big change, but it actually simplifies display list generation.

Two related fixes for border-collapse:
* Fix border collapsing across table-row-group flows
This fixes the border-end calculation for table rows whose borders are collapsed with rows in different rowgroups. The border collapsing code now uses an iterator that yields all the rows as a flat sequence, regardless of how they are grouped in rowgroups. It gets rid of `TableRowGroupFlow::preliminary_collapsed_borders` which was never correct. (It was read but never written.)
This may fix#8120 but I'm not 100% certain. (I haven't managed to reproduce the intermittent failure locally, and my reduced test case still fails but in a different way.)
* Fix confusing `push_or_mutate` API
This fixes a bug when recalculating border collapsing for an existing table row. The bug was caused by using `push_or_mutate` which has no effect if there is already a value at the specified index.
The fix switches incorrect `push_or_mutate` calls to use `push_or_set` instead. It also renames `push_or_mutate` to `get_mut_or_push` which I think is a less-confusing name for this method.

Instead, schedule a delayed composite after each frame of an animation.
The previous code would cause jank, because the following sequence
frequently occurred:
1. The page uses `requestAnimationFrame()` to request a frame.
2. The compositor receives the message, schedules a composite,
dispatches the rAF message to the script thread, composites, and goes to
sleep waiting for vblank (frame 1).
3. The script makes a change and sends it through the pipeline.
Eventually it gets painted and is sent to the compositor, but the
compositor is sleeping.
4. The compositor wakes up, sees the new painted content, page flips,
and goes to sleep (frame 2). Repeat from step 1.
The problem is that we have two composition frames, not just one. This
halves Web apps' framerate!
This commit fixes the problem by scheduling the composite in step 2 to
12 ms in the future. We already have this delayed-composition
functionality in the form of the scrolling timer, which I repurposed and
renamed to the "delayed composition timer" for this task. This change
gives the page 12 ms to prepare the frame, which seems to usually be
enough, especially with WebRender.
Note that simply removing the scheduled composite after rAF is not the
correct solution. If this is done, then pages that call rAF and don't
modify the page won't receive future rAFs, since the compositor will be
sleeping and won't be notified of vblank.
Fixes a bunch of jank in browser.html. The remaining jank seems to be a
problem with browser.html itself.
