e0bd80f807 Auto merge of #6662 - tschneidereit:client-geometry, r=glennw,pcwatson
Implement Element.client{Top,Left,Width,Height}

This isn't done, but contains a working implementation of at least `clientTop`. Feedback would be much appreciated: it's probably far from ideal.

Implementing `clientLeft` is straight-forward, I think, but `clientWidth` and `clientHeight` require accessing the `border_box` - and I don't know how that works, yet.

82b53d83ff script: Make the ImageCacheTask use IPC.
This necessitated getting rid of the boxed trait object that was being

bb99b2f3c8 script: Make most of 2D canvas and WebGL run over IPC.
To actually make the multiprocess communication work, we'll need to
reroute the task creation to the pipeline or the compositor. But this
works as a first step.

f6525b8009 Register/unregister memory reporters in a better place.
By doing this on either side of the call to the relevant tasks' start()
method, we don't need to store the mem::ProfilerChan or the reporter
name in the task itself.

6eacb0c995 gfx: Make display lists serializable using serde.
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.

e5b1ec4078 script: Split Pipeline::create into chrome process and content
process parts.

This will make it easier to adapt to IPC.

The trickiest part here was to make script tasks spawn new layout tasks
directly instead of having the pipeline do it for them. The latter
approach will not work in multiprocess mode, because layout and script
must run in the same address space and the pipeline cannot inject tasks
into another process.

b876a54dce Auto merge of #6365 - pcwalton:sequential-display-list-construction, r=larsbergstrom
layout: Disable parallel display list building by default.

I've never see it result in a speedup. Actually, I don't think I've seen
it result in anything better than a 50% slowdown. The arithmetic
intensity is just too low, at least with the current algorithm.

Parallel DL building can still be enabled with a debug flag if the
algorithm is improved.

d0a29c3951 Use a dedicated type for the opaque type parameter to WorkQueue in layout.
Currently, we use UnsafeFlow and UnsafeLayoutNode, both of which are aliases

48a0725c01 Measure LocalLayoutContexts in LayoutTask and LayoutWorkers.
The FreeType instances in layout workers are reasonably large and worth
measuring. The one in LayoutTask is smaller but it's easy to measure at the
same time. Sample output:

|             0.30 MiB -- display-list
|             0.07 MiB -- local-context
```
This required adding a mechanism to WorkQueue to measure worker TLSes.

4f47b41fa7 Remove fnv & smallvec crate reexports from util
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.

0dec64caf0 Auto merge of #6289 - nnethercote:unleak-LOCAL_CONTEXT_KEY, r=pcwalton
`LOCAL_CONTEXT_KEY` is currently a `Cell<*mut LocalLayoutContext>`. The use
of the raw pointer means that the `LocalLayoutContext` is not dropped when
the thread dies; this leaks FreeType instances and probably other
things. There are also some unsafe getter functions in `LayoutContext`
(`font_context`, `applicable_declarations_cache` and
`style_sharing_candidate_cache`) that @eddyb says involve undefined
behaviour.

This changeset changes `LOCAL_CONTEXT_KEY` to
`RefCell<Option<Rc<LocalLayoutContext>>>`. This fixes the leak and also
results in safe getters.

(Fixes #6282.)

af364a412e Audit and reduce unstable usage in layout
Reasons behind existing unstable features:

alloc:

 - `make_unique()`
 - direct calls into `heap::allocate()`, etc
 - `boxed::into_raw()` (naming)

collections:

 - `slice_chars()` (needs to prove its worth)

core:

 - lots and lots of pointer manip
 - `raw` stuff

std_misc:

 - Handle stuff
 - hasher stuff

str_char:

 - CharRange

f47ba6fd33 First step towards 3d transforms.
* Add parser support for 3d transforms.
 * Change ComputedMatrix to a representation that suits interpolation.
 * Switch stacking contexts to use 4x4 matrices.

The transforms themselves are still converted to 2d and handled by azure for now, but this is a small standalone part that can be landed now to make it easier to review.

5e61ebaa05 Auto merge of #6031 - glennw:reftest-race-conditions, r=larsberg,jdm
The basic idea is it's safe to output an image for reftest by testing:
 - That the compositor doesn't have any animations active.
 - That the compositor is not waiting on any outstanding paint messages to arrive.
 - That the script tasks are "idle" and therefore won't cause reflow.
    - This currently means page loaded, onload fired, reftest-wait not active, first reflow triggered.
    - It could easily be expanded to handle pending timers etc.
 - That the "epoch" that the layout tasks have last laid out after script went idle, is reflected by the compositor in all visible layers for that pipeline.
