24730f1078 Borrow the QueueData for WorkQueue::run.
This allows us to get rid of the raw pointers and unsafe dereferencing in
the parallel layout implementation.

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.

9b4d39d6d1 Make LOCAL_CONTEXT_KEY safe and non-leaky.
`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.)

7e7675c1dc net: Don't load the placeholder image for background images, only for
image fragments.

This also changes the way the placeholder is handled in the image cache
task to decode it up front instead of each time an image fails to load,
both because it was more convenient to implement that way and because
it saves CPU cycles to do so.

This matches the behavior of Gecko and WebKit. It improves the look of
our cached copy of Wikipedia.

a5a5214783 Various fixes to getClientBoundingRect()
* Fix queries involving stacking contexts
 * The code was double accumulating stacking context origins.
* Handle queries of inline elements.
 * The node addresses being compared were incorrect (CharacterData vs. Span)
* Handle ScriptQuery reflows correctly.
 * The layout task was skipping the compute absolute positions traversal, so failed before window.onload.

d8aef7208e Refactored image cache task - details below.
* Simpler image cache API for clients to use.
 * Significantly fewer threads.
   * One thread for image cache task (multiplexes commands, decoder threads and async resource requests).
   * 4 threads for decoder worker tasks.
 * Removed ReflowEvent hacks in script and layout tasks.
   * Image elements pass a Trusted<T> to image cache, which is used to dirty nodes via script task. Previous use of Untrusted addresses was unsafe.
   * Image requests such as background-image on layout / paint threads trigger repaint only rather than full reflow.
 * Add reflow batching for when multiple images load quickly.
   * Reduces the number of paints loading wikipedia from ~95 to ~35.
 * Reasonably simple to add proper prefetch support in a follow up PR.
 * Async loaded images always construct Image fragments now, instead of generic.
   * Image fragments support the image not being present.
 * Simpler implementation of synchronous image loading for reftests.
 * Removed image holder.
 * image.onload support.
 * image NaturalWidth and NaturalHeight support.
 * Updated WPT expectations.

66dd8c8a6c layout: Implement CSS transitions per CSS-TRANSITIONS § 2.
Transition events are not yet supported, and the only animatable
properties are `top`, `right`, `bottom`, and `left`. However, all other
features of transitions are supported. There are no automated tests at
present because I'm not sure how best to test it, but three manual tests
are included.

fafc357308 Fix broken viewport percentage length units after a viewport resize.
When a viewport is resized, the computed values for a style containing viewport percentage length units become stale. However, there's no way for those styles to be invalidated after a resize. As a solution, this commit invalidates the computed values cache after a resize has occurred, which is probably over-kill.

A better solution would probably be to track under what conditions computed values remain valid, and invalidate them as indicated.

d12c6e7383 Incremental Style Recalc
This patch puts in the initial framework for incremental reflow. Nodes' styles
are no longer recalculated unless the node has changed.

I've been hacking on the general problem of incremental reflow for the past
couple weeks, and I've yet to get a full implementation that actually passes all
the reftests + wikipedia + cnn. Therefore, I'm going to try to land the different
parts of it one by one.

This patch only does incremental style recalc, without incremental flow
construction, inline-size bubbling, reflow, or display lists. Those will be coming
in that order as I finish them.

At least with this strategy, I can land a working version of incremental reflow,
even if not yet complete.
