WebRender is an experimental GPU accelerated rendering backend for Servo.
The WebRender backend can be specified by running Servo with the -w option (otherwise the default rendering backend will be used).
WebRender has many bugs, and missing features - but it is usable to browse most websites - please report any WebRender specific rendering bugs you encounter!
Use SIMD in fast path for advance_for_char_range
In advance_for_char_range add a fast SIMD code path for the the common
case where there are no detailed glyphs.

- SIMD isn't used on non-x86_65/aarch64 architectures.
This commit introduces the `serde` dependency, which we will use to
serialize messages going between processes in multiprocess Servo.
This also adds a new debugging flag, `-Z print-display-list-json`,
allowing the output of display list serialization to be visualized.
This will be useful for our experiments with alternate rasterizers.
Move LayerBuffer cache to the compositor
Now that NativeDisplay can be shared between the compositor and the
paint task, we can move the LayerBuffer cache to the compositor. This
allows surfaces to be potentially reused between different paint tasks
and will eventually allow OpenGL contexts to be preserved between
instances of GL rasterization.

This will allow reporting of memory usage by FreeType instances, which
are measured in the MiBs for LayoutWorker threads.
This change also makes FreeType allocations happen with jemalloc instead
of the system malloc, which is a good thing.
Finally, the change documents some dubiousness involving
FontContextHandle.
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.
Reasons behind existing unstable features:
alloc:
- weak pointers (may not belong)
- boxed::into_raw and from_raw (naming)
collections:
- `Vec.push_all()` (May be replaced)
- Replace with loop
core:
- `min_by` (#15311)
- `PI_2` (naming)
rustc_private:
- FnVHasher
- Can be replaced by rust-fnv
std_misc:
- Hash state stuff (no option here unless we want to stop using it)
str_char:
- CharRange usage
- Can be replaced by regular iterators (char_indices)
Example output from the memory profiler:
```
| 1.04 MiB -- url(http://en.wikipedia.org/wiki/Main_Page)
| 0.26 MiB -- display-list
| 0.78 MiB -- paint-task # new output line
| 0.78 MiB -- buffer-map # new output line
```
The buffer maps aren't huge, but they're worth measuring, and it's good
to get the memory profiler plumbing into PaintTask.
