These are the interdependent patches of Bug 1335998. We want to do interpolation and accumulation for mismatched transform lists, so introduce ComputedOperation::InterpolateMatrix and ComputedOperation::Accumulation. Both arms store the from_list and to_list, and resolve them until we have the layout information. For the Servo part, we haven't implemented how to read the transform lists in layout/fragment.rs, but I think it would be easy. (related issue #13267)

-moz-transform property is an alias shorthand property. It has transform as sub-property but their parsing is different in some cases(matrix/matrix3d). -moz-transform also accepts LengthOrPercentage in the nondiagonal homogeneous components of matrix and matrix3d.
It looks like length and percentage values are getting computed to number directly. For example 120px converts into 120 and calc(120px + 20%) converts into 140. So I did like this. But we need to check this behavior again to be sure, I guess.
Also I spent half day investigating why matrices are not serializing after this change and found out their ToCss functions is not completely implemented yet 😄 I was going to implement them but there is an easy issue about it(#15194) so I left it that way. Probably all tests won't pass without it.

The design of initiating network requests from the image cache thread was simple, but it makes it difficult to implement image loading that conforms to the HTML specification. These changes make the implementation of HTMLImageElement responsible for network requests for `<img>` elements, and CSS-based images (background-image, bullets, etc.) are requested by the script thread to ensure that the layout thread does not attempt to retain unsafe pointers to DOM nodes during asynchronous operations.

When calculating size of replaced element that has intrinsic aspect ratio, we need to multiply the ratio if one of the dimensions has definite size. And we can not precompute the ratio and store it as a float, because doing so may result one pixel difference in calculation for certain images, thus make some tests fail. So it may overflow when the dimension lengths are large, and this pull request convert them to `i64` before multiplication.

According to https://github.com/servo/servo/pull/3069 the cached thread local context is introduced for green threads. Now green threads has gone, and the existence of cache force us to create a `LayoutContext`, an `AssignISizes` and an `AssignBSizes` for each flow during parallel layout, so the pull request tries to remove it. And it also switch `assign_inline_sizes()` to accept a `LayoutContext` parameter, as according to my current design we need to do full layout to some flex items for column flexbox during assign isize traversal.

This patch allows Servo to incrementally reflow truncated fragments correctly.
* The untruncated version of a fragment is preserved, and when incrementally reflowing, the untruncated version is what gets reflowed. If it needs truncated, it will get truncated again.
* The ellipsis fragments are skipped when incrementally reflowing a line. If it is still needed, it will be recreated.

The primary idea of this patch is to ditch the rigid enum of Previous/Current
styles, and replace it with a series of indicators for the various types of
work that needs to be performed (expanding snapshots, rematching, recascading,
and damage processing). This loses us a little bit of sanity checking (since
the up-to-date-ness of our style is no longer baked into the type system), but
gives us a lot more flexibility that we'll need going forward (especially when
we separate matching from cascading). We also eliminate get_styling_mode in
favor of a method on the traversal.
This patch does a few other things as ridealongs:
* Temporarily eliminates the handling for transfering ownership of styles to the
frame. We'll need this again at some point, but for now it's causing too much
complexity for a half-implemented feature.
* Ditches TRestyleDamage, which is no longer necessary post-crate-merge, and is
a constant source of compilation failures from either needing to be imported
or being unnecessarily imported (which varies between gecko and servo).
* Expands Snapshots for the traversal root, which was missing before.
* Fixes up the skip_root stuff to avoid visiting the skipped root.
* Unifies parallel traversal and avoids spawning for a single work item.
* Adds an explicit pre_traverse step do any pre-processing and determine whether
we need to traverse at all.

<!-- Please describe your changes on the following line: -->
Don't promote all scrollable regions to stacking contexts
Instead annotate all flows with their owning ScrollRoots. When
processing the display list items into a flattened display list, we add
PushScrollRoot and PopScrollRoot to signal when scrolling regions start
and end. It is possible for content from different scrolling regions to
intersect and when they do, the stack of scrolling regions is
duplicated. When these duplicated scrolling regions stacks reach
WebRender, it will scroll them in tandem.
The PushScrollRoot and PopScrollRoot items are currently represented as
StackingContexts in WebRender, but eventually these will be replaced
with special WebRender display items.

We need to hang both snapshots and restyle damage off of ElementData, and so we need them to be concrete to avoid infecting ElementData with the trait hierarchy.

Migrated the trace-layout code from old `rustc-serialize` to `serde_json`. This will help us iterate faster on the layout viewer (#13432), #13436, #12675 and fix#12936.
