* feat: Support font-relative `ch` and `ic` units
After #31966, which made it possible for the first time to resolve
font-relative CSS units, this change adds support for the `ch` and
`ic` units.
One difference with the `ex` unit that was added in that PR is that
these units must reflect the advance width of a character (the zero
digit in the case of `ch`, and the CJK water radical for `ic`) as it
would be rendered by the current font group. This means that the size
of these units don't only depend on the first available font, in the
case where that font does not contain a glyph for that character.
This is implemented by adding the advance width for these two
characters as optional fields of `FontMetrics`, so the advance width
computation happens in advance. Then, when the font metrics are
queried as part of unit resolution, the font group is searched for the
first font containing that character.
This change only implements support for these units in upright
typesetting modes, since Servo does not yet have support for vertical
writing modes. This means that many of the WPT tests that test for the
behavior of these units with vertical writing modes do not pass.
This change also makes a number of WPT tests pass, which relied on the
`ch` and `ic` units. It, however, also makes the test
`/css/css-text/white-space/text-wrap-balance-overflow-002.html` fail,
since it tests `text-wrap: balance`, which Servo does not yet
implement, and it was only previously passing by chance due to the
previous behavior of these units.
* Revert Python 3.10-related changes to wss
* Fix formatting
* Remove test expectation
There are a couple major changes here:
1. Support is added for the `weight`, `style`, `stretch` and
`unicode-range` declarations in `@font-face`.
2. Font matching in the font cache can return templates and
`FontGroupFamily` can own mulitple templates. This is due to needing
support for "composite fonts". These are `@font-face` declarations
that only differ in their `unicode-range` definition.
This fixes a lot of non-determinism in font selection especially when
dealing with pages that define "composite faces." A notable example of
such a page is servo.org, which now consistently displays the correct
web font.
One test starts to fail due to an uncovered bug, but this will be fixed
in a followup change.
Fixes#20686.

While <https://drafts.csswg.org/css-lists/#list-style-position-property> says:
> The size or contents of the marker box may affect the height of the
> principal block box and/or the height of its first line box, and in some
> cases may cause the creation of a new line box; this interaction is also
> not defined.
All other browsers ensure that the first line of list item content is
the same block size as the marker. Doing this is complicated, but we can
ensure that the entire list item is at least as tall as the marker. This
should handle the majority of cases and we can make refinements later
for stranger situations, such as when the marker is very tall.

Bumps Stylo to servo/stylo#37
`white-space` is split into `white-space-collapse` and `text-wrap-mode`:
| white-space | white-space-collapse | text-wrap-mode |
| ----------- | -------------------- | -------------- |
| normal | collapse | wrap |
| nowrap | collapse | nowrap |
| pre-wrap | preserve | wrap |
| pre | preserve | nowrap |
| pre-line | preserve-breaks | wrap |
| - | preserve-breaks | nowrap |
Note this introduces a combination that wasn't previously possible,
but I think the existing logic can handle it well enough.
The old `allow_wrap()` is replaced by checking whether `text-wrap-mode`
is set to `wrap`.
The old `preserve_newlines()` is replaced by checking whether
`white-space-collapse` is *not* set to `collapse`.
The old `preserve_spaces()` is replaced by checking whether
`white-space-collapse` is set to `preserve`.

Tables should always be at least as big as their min-content size, even
if we would expect a smaller size according to CSS sizing properties.
#31455 implemented it for in-flow tables participting in flow layout,
but a few cases remained. This patch addresses floated tables.
Previously, the "scroll to fragment" operation could scroll past the end
of the screen, because the scroll position was not clamped to viewport
boundaries. Correct this by using the `Window::scroll()` method which
handles this case.
In addition, ensure that `Window`'s `current_viewport` member is
initialized properly when it is created.
This change adds very basic support for `list-style-position`.
Currently, the marker does not do any kind of baseline alignment with
the rest
of the list item contents and it also doesn't force the list item to be
at least as tall as the marker.
This adds a few new failures:
- Four failures because markers do not ensure that list-items have at
least the same block size as they do:
- FAIL [expected PASS] /css/CSS2/lists/list-style-applies-to-012.xht
- FAIL [expected PASS] /css/CSS2/lists/list-style-applies-to-014.xht
- FAIL [expected PASS]
/css/CSS2/lists/list-style-type-applies-to-012.xht
- FAIL [expected PASS]
/css/CSS2/lists/list-style-type-applies-to-014.xht
- One failure because we don't yet support the `::marker`
pseudo-selector:
- FAIL [expected PASS]
/css/css-position/position-absolute-dynamic-list-marker.html
- One failure because we don't support the list item exception for the
line height quirk:
- FAIL [expected PASS] /quirks/line-height-in-list-item.tentative.html

This fixes several tests in
[wpt/user-timing](https://wpt.fyi/results/user-timing?label=master&product=chrome%5Bexperimental%5D&product=firefox%5Bexperimental%5D&product=safari%5Bexperimental%5D&product=servo&aligned)
by fixing some logic errors in how marks/measures are cleared (via
[`clearMarks`](https://developer.mozilla.org/en-US/docs/Web/API/Performance/clearMarks)
and
[`clearMeasures`](https://developer.mozilla.org/en-US/docs/Web/API/Performance/clearMeasures)).
There are two changes:
1. Fix the boolean logic in `clear_entries_by_name_and_type` so that,
when `clearMarks('foo')` or `clearMeasures('foo')` is called, the
presence of the entry name correctly filters based on existing entry
names.
2. Make the `entry_name` param a `DOMString` rather than an
`Option<DOMString>` since every API call has it as `Some` anyway, and
I'm not aware of any [Performance
APIs](https://developer.mozilla.org/en-US/docs/Web/API/Performance)
where you can clear all entries regardless of type. (This is not
strictly required for the fix, but I think it makes the code easier to
read.)
~~I also considered adding the expected WPT results using `mach
update-wpt`. But I'm not sure if you want these changes, since the
expectations are currently missing (i.e. `tests/wpt/meta/user-timing`
does not exist).~~ (_Update: added!_)
For the record, this PR fixes the following tests:
- `clearMarks.html.ini`
- `clearMeasures.html.ini`
- `clear_non_existent_mark.any.js.ini`
- `clear_non_existent_measure.any.js.ini`
- `clear_one_mark.any.js.ini`
- `clear_one_measure.any.js.ini`

A `TextRun` is composed of `TextRunSegment`s that are composed of
`GlyphRun`s.
`TextRun::glyph_run_is_preserved_newline` is indexing into the `TextRun`
text, but the `GlyphRun` indexes that it uses are relative to the
`TextRunSegment`
offset. Before the code was using the offset without incorporating the
`TextRunSegment` offset. This led to miscalculation of preserved newline
location while processing text content.

`<br>` elements are a bit "special" in the sense that they defer a
linebreak, but can also have `clear` applied to them. The `clear` that
they supply should be applie *after* the linebreak is processed. This
change adds special processing for this situation.
Fixes#15402.
The logic was to remove any collapsible white space preceded by other
white space. However, this should only happen if the preceding space
is also collapsible.
Also fixing the logic in ContentSizesComputation, which was wrong
but previously it didn't matter.
If the top and bottom margins of an element collapse through, then this
patch treats the bottom margin as collapsing with its children, even if
`height` doesn't compute to zero.

The top and bottom margins of an element can collapse through if its
height is auto or zero. Indefinite percentages behave as auto, so they
shouldn't prevent the margins from collapsing.

The only font relative unit that Servo knows how to resolve currently is
`rem` (relative to the root font size). This is because Stylo cannot do
any font queries. This adds a mechanism to allow this, exposing the
ability to properly render `ex` units in Servo.
This change only allows resolving some font size relative units thoug,
as Servo doesn't collect all the FontMetrics it needs to resolve them
all. This capability will be added in followup changes.
Some new tests fail:
- ex-unit-001.html: This test fails because Servo does not yet have
support for setting the weight using @font-face rules on web fonts.
- ex-unit-004.html: This test fails because Servo does not yet have
support for setting the Unicode range of a web font using @font-face
rules.
- first-available-font-001.html: This test fails because the above
two feature are missing.
WebRender does not preserve spatial tree offsets when updating the
spatial tree. Updating the spatial tree of a pipeline can also
update the spatial tree of child pipelines. This change ensures that
WebRender always gets the scroll offsets of the entire scene when
modifying display lists in a way that may rebuild the spatial tree.
Fixes#31807.
* Ignore spaces before atomic inline for the min-content size
For the min-content size we should wrap lines wherever is possible,
so wrappable spaces shouldn't increase the length of the line,
they will just be removed or hang at the end of the line.

This requires passing through information about whether or not the
element in question is replaced when checking to see if it's
transformable and transitively all functions that make decisions about
containing blocks. A new FragmentFlag is added to help track this -- it
will be set on both the replaced items BoxFragment container as well as
the Fragment for the replaced item itself.
Fixes#31806.
This change also makes two fixes that are necessary to get WOFF2 fonts
working:
1. It adds support for loading web fonts from stylesheets included via
@import rules.
2. It ensure that when web fonts are loaded synchronusly they invalidate
the font cache. This led to incorrect font rendering when running
tests before.
Fixes#31598.
Instead of replacing Stylist's device on every reflow, only replace it
when the viewport changes. In addition, preserve the root font size from
the previous reflow fixing an issue where `rem` units were not properly
computed between reflows.
This fixes a bug where fonts that are sized using `rem` units change
size on reload.
