Without this change, each text fragment in a block that establishes a
stacking context will establish its own stacking context. This is
unnecessary and increases the amount of work done during display list
construction. This change should not change output, but should improve
performance.

This happens asynchronously, just as it does in non-WebRender mode.
This functionality is a prerequisite for doing proper display-list-based
hit testing in WebRender, since it moves the scroll offsets into Servo
(and, specifically, into the script thread, enabling iframe event
forwarding) instead of keeping them private to WebRender.
Requires servo/webrender_traits#55 and servo/webrender#277.
Partially addresses #11108.

This is used as a fallback for any characters that don't have glyphs in the specified font. Without this, per-glyph font fallback doesn't work because the FontGroup always contains only one font. Fixes missing glyphs on many pages on my Linux box.
As a follow-up, we should probably have a smarter strategy for finding fallback fonts, possibly varying by script. (Currently we just have a few hard-coded family names.)

The whitespace range was not properly shifted which caused us to adjust the fragment's inline size by the advance of a different set of characters.
This was causing justified text lines to be too long or too short.

LineBreaker calls Fragment::strip_trailing_whitespace_if_necessary and then recalculates the fragment's inline size. But this isn't necessary because strip_trailing_whitespace_if_necessary already recalculates the size.

This is a work-in-progress that:
* Adds support for some pseudo-elements to skip the cascade entirely, in an analogous way to Gecko's anonymous box pseudo-elements.
* Takes rid of `StylistWrapper`, and uses `Arc::get_mut` instead.
* Uses the first bullet to precompute the `-servo-details-content` pseudo's style.
I'd like @bholley to take a look before following, do you think that the aproach is the correct?
Also, @SimonSapin could want to put some eyes on it.

Replace character indices with UTF-8 byte offsets throughout all code dealing with text runs. This eliminates a lot of complexity when converting from one to the other, and interoperates better with the rest of the Rust ecosystem.
For most code this is just a simple replacement of char indices with byte indices. In a few places like glyph storage and text fragment scanning, it also lets us get rid of code that existed only to map between bytes and chars.
Also includes some related fixes to text shaping, discovered while working on this conversion. See the commit messages for details.

Fixes#10200. r? @pcwalton
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
months ago.

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.

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.

This fixes about 130 clippy lints. Let me know if i should split up the commit.
I wasn't sure about some of the changes, especially map_or instead of map(...).unwrap_or(...) and if let instead of single arm match were not always a strict improvement in my opinion, but i'll leave that decision to the reviewer :)
There are about 150 lints left which i thought were clippy bugs or i didn't know how to fix.

This gets us to where we need to be in order to write a Gecko implementation of the layout wrapper and have things Just Work.
Note that this is somewhat more than we need for just running the style system. But there wasn't a clean place to cut, and I thought it was a good idea to just do a complete job on it now, which may save us effort and mismatches in the long run.

The RECONSTRUCT_FLOW restyle damage bit shouldn't apply to newly
constructed flow tree elements. It is explicitly removed for Flows, but
not for Fragments. This causes RECONSTRUCT_FLOW to bubble up to Flows
that contain any Fragments at all. Instead explicitly remove the
RECONSTRUCT_FLOW bit when creating a new Fragment.
There isn't a good way to test this currently, but all tests should
continue to pass.
