Previously, the code that called this function was responsible for this.
Some code paths neglected to do it. This moves the damage removal to one
central location.
WebRender.
This happens asynchronously, just as it does in non-WebRender mode.
This functionality is a prerequisite for doing proper display-list-based
hit testing in WebRender, since it moves the scroll offsets into Servo
(and, specifically, into the script thread, enabling iframe event
forwarding) instead of keeping them private to WebRender.
Requires servo/webrender_traits#55 and servo/webrender#277.
Partially addresses #11108.
The previous code assumed that the diagonals of the elements were
perpendicular, which only happens with squares.

Use byte indices instead of char indices for text runs
Replace character indices with UTF-8 byte offsets throughout all code dealing with text runs. This eliminates a lot of complexity when converting from one to the other, and interoperates better with the rest of the Rust ecosystem.
For most code this is just a simple replacement of char indices with byte indices. In a few places like glyph storage and text fragment scanning, it also lets us get rid of code that existed only to map between bytes and chars.
Also includes some related fixes to text shaping, discovered while working on this conversion. See the commit messages for details.

Merge DisplayListEntry into DisplayItem
We don't really need two levels of abstraction for every element in the
DisplayList. This simplifies the complexity of the data structure in
preparation for providing documentation and properly handling scrolling
roots.

set to be scrolled.
This makes them establish stacking contexts, which is a CSS 2.1 spec
violation. However, we were already violating the spec here for
absolutely-positioned elements with `overflow: scroll`. It will probably
be easier to fix this spec violation once we either switch entirely to
WebRender or we have multiple layers per stacking context.
Closes#2742.
Move some CSS properties to match Gecko's representation
Fixes#10403. Animation had an extra transition-delay property, which was also moved to Box. Let me know if I should squash the commits.

ComputedValues is now ServoComputedValues
This is the first part of #10185. More to follow. I have built this locally with both servo and geckolib without errors; let's see if it succeeds on all platforms as well.

Highlight selected text in input fields
Fixes#9993. This does not yet allow stylesheets to set the selection colors; instead it uses a hard-coded orange background and white foreground.

Generalize the style structs
This allows geckolib to pass gecko style structs and have the style system write to them directly, provided we implement all the traits.

over the data as well.
WebRender doesn't need the data, as it acquires it separately.
About a 50%-100% improvement in display list building time on
browser.html.
Now that WebRender uses an Iframe display item, we do not need the Noop
item for the non-WebRender path. We can simply reuse the Iframe display
item. Also remove the layer_id member from the LayeredItem struct, as
it is unused.
