In order to properly handle CSS clipping, we need to keep track of what
the different kinds of clips that we have. On one hand, clipping due to
overflow rules should respect the containing block hierarchy, while CSS
clipping should respect the flow tree hierarchy. In order to represent
the complexity of items that are scrolled via one clip/scroll frame and
clipped by another we keep track of that status with a
ClipAndScrollInfo.
The traversal currently expects every flow to have a scroll root id
assigned, even if it doesn't produce any display items. This change
fixes the error that arises from this situation.
This only makes use of the "Solid" text decoration type, which
matches the existing support. WR now supports dotted, dashed
and wavy text decorations, but supporting those will need some
extra work in Servo to pass through the correct values.
Revert "Backed out changeset b10e6ba9cbdb because gecko part had to b…
…e backed out."
This reverts commit b96d96d448.
The fix on the Gecko side is trivial, and I can land it after this lands.

The alias is left there temporarilly and will be removed completely in a later commit where
also components/style/gecko/generated/structs_{debug|release}.rs are re-generated (they still
use the old alias).
Also includes an incidental bugfix for the rendering order of text decorations.
This change depends on servo/webrender#1454 being merged and upstreamed to servo.
This allows us to have ensure_data() and clear_data() functions on the TElement
trait, instead of hacking around it adding methods in random traits.
This also allows us to do some further cleanup, which I'd rather do in a
followup.
Fix the size and position of overflow:scroll clip
The clip for overflow:scroll clip was not including the space for
padding, which could lead to some content being clipped when it
shouldn't. This changes fixes that issue.
A test is skipped because this fix also stops hiding a failure due to
mispositioned text.
Fixes#16576.

layout: Stop in-order traversal on children of InlineFlow
No need to do in-order traversal for children of InlineFlow, since
they are either inline-block or absolutely positioned elements, which
are guaranteed to be block formatting context.

This reverts commit ebfc8f5858, reversing
changes made to 5585ff2c44.
Animation code can reenter and create a new TLS context from the traversal
SequentialTask, so this won't work as written.
layout: Clean up inline_metrics_of_block a little.
Previously the variable names were a little confusing (ascent was used
for the space_above_baseline in one branch and the and ascent field in
another branch, and was not really the ascent in one). Also add a
small diagram.

Fix incremental layout bugs for absolute and cleared elements
Fixes#17307. <del>There were two underlying bugs:</del>
* <del>Nodes were not marked dirty when their style attribute changed.</del>
* BaseFlow flags set during flow construction could get out of sync with the element's style if repair_style was called.
