These are the inter-dependent patches of bug 1392161. We want to handle
extreme small lengths carefully for some properties, such as transform, so we
shouldn't use |Au| as the computed value of specified::Length. Now, we introduce
a new type, CSSPixelLength, which is a wrapper of CSSFloat, and it is the
computed value of specified::Length, so we can keep the fractional part
of computed::Length.

WR now has a concept of font templates and font instances. This
makes the WR font interfaces closer to Cairo and Gecko, and also
makes some future performance optimizations possible.
A font template is the font family, and data backing the font.
A font instance is a reference to a font template and per-instance
options, such as font size, anti-aliasing settings etc.
To update Servo in a minimally invasive way, I added a new font
cache call, that creates a font instance. This means that when
a font is created, and doesn't exist in the cache there are now
two calls to the font cache thread. We could refactor the font
cache to make this work in one call, which we should do in the
future. However, refactoring the font cache is a large chunk of
work by itself. The extra call is only when a font doesn't already
exist in the font context cache, so it should have minimal
performance impact.

Some properties only accept non-negative values, or values greater than or equal to one. It is possible to produce an negative interpolated values while using negative timing functions, so we have to apply a restriction to these values to avoid getting invalid values.
For example, line-height must be non-negative, but the output progress of some timing functions (e,g. cubic-bezier(0.25, -2, 0.75, 1)) may be a negative value, so the interpolated result of line-height is also negative.

This removes paint threads, rust-layers dependency, and changes
optional webrender types to be required.
The use_webrender option has been removed, however I've left
the "-w" command line option in place for now so that wpt
runner can continue to pass that. Once it's removed from there
we can also remove the -w option.
Once this stage is complete, it should be fine to change the
display list building code to generate webrender display
lists directly and avoid the conversion step.

Background:
The changes to Servo code to support Stylo began in the `selectors` crate with making pseudo-elements generic, defined be the user, so that different users (such as Servo and Gecko/Stylo) could have a different set of pseudo-elements supported and parsed. Adding a trait makes sense there since `selectors` is in its own repository and has others users (or at least [one](https://github.com/SimonSapin/kuchiki)).
Then we kind of kept going with the same pattern and added a bunch of traits in the `style` crate to make everything generic, allowing Servo and Gecko/Stylo to do things differently. But we’ve also added a `gecko` Cargo feature to do conditional compilation, at first to enable or disable some CSS properties and values in the Mako templates. Since we’re doing conditional compilation anyway, it’s often easier and simpler to do it more (with `#[cfg(feature = "gecko")]` and `#[cfg(feature = "servo")]`) that to keep adding traits and making everything generic. When a type is generic, any method that we want to call on it needs to be part of some trait.
----
The first several commits move some code around, mostly from `geckolib` to `style` (with `#[cfg(feature = "gecko")]`) but otherwise don’t change much.
The following commits remove some traits and many type parameters through the `style` crate, replacing them with pairs of conditionally-compiled API-compatible items (types, methods, …).
Simplifying code is nice to make it more maintainable, but this is motivated by another change described in https://github.com/servo/servo/pull/12391#issuecomment-232183942. (Porting Servo for that change proved difficult because some code in the `style` crate was becoming generic over `String` vs `Atom`, and this PR will help make that concrete. That change, in turn, is motivated by removing geckolib’s `[replace]` override for string-cache, in order to enable using a single Cargo "workspace" in this repository.)

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.)

This works best with https://github.com/servo/mozjs/pull/71, too, to enable static linking, but can be run without (via some PATH hackery).

Hi guys,
I just gave a big pass of RFC-0344 as per issue #6224 .
Pretty much renamed all the get_* fn that were used to fetch values.
I hope I didn't rename too much.
As said in the issue discussion, I didn't touch at the scripts folder so we keep the unsafe ones pretty explicit.
I've ran the whole pass of test, everything seems to be still working right :).
Please give feedback on this PR.
Thanks for looking into it.

The util component specified fnv and smallvec as dependencies and publicly
reexported both of them. Several other components utilized these reexports,
presumably because fnv and smallvec used to live in the tree so reexporting
made the transition easier.
These indirect dependencies through the util component are unnecessary.
This commit removes the fnv & smallvec crate reexports in the util component.
It exchange, it adds fnv & smallvec as dependencies to non-util components
wherever needed. Finally, it removes the fnv dependency from util as it is not
utilized anywhere in the util component.

There are several optimizations here:
* We make font families atoms, to allow for quicker comparisons.
* We precalculate an FNV hash of the relevant fields of the font style
structure.
* When obtaining a platform font group, we first check pointer equality
for the font style. If there's no match, we go to the FNV hash. Only
if both caches miss do we construct and cache a font group. Note that
individual fonts are *also* cached; thus there are two layers of
caching here.
