The grammar groups this component together meaning that all
sub-components must occur together i.e.
`ordinal slashed-zero small-caps` is valid but
`ordinal small-caps slashed-zero` is not.
We also reuse the logic for parsing from the longhand
`font-variant-numeric` property for simplicity.

`common-ligatures small-caps no-contextual` is not.

`none` isn't a supported value for `<counter-style-name>` and is only
supported directly by `list-style-type` (i.e. not within `counter{s}()`
functions)
This means we now allow oblique angles when parsing the `font`
shorthand.
This also required us to rename the existing `FontStyle` enum to
`FontStyleKeyword`
Previously this was implemented inline within the parsing of
`{repeating}-radial-gradient()` functions but it will also be useful for
`circle()` and `ellipse()`.
We now support the CSS Images Module Level 4 additions to the
`<radial-size>` syntax, namely:
- `<length-percentage>` rather than just `<length>` for circles.
- Distinct `<radial-extent>` values for horizontal and vertical for
ellipses.
- Mixing of `<radial-extent>` and `<length-percentage>` values for
ellipses.
The regressions are due to WPT not being updated to expect the first of
these additions.
Storing these within `LengthPercentage`, `LengthBox`, and `Variant`
over-complicated things.
We also now use the correct `SerializationMode` when serializing `xywh`
and `rect`
This excludes `step-end` and `step-start` which are expected to be
converted to the equivalent function at parse time.
We are expected to serialize these as the explicit keywords - previously
we would parse as `EasingStyleValue` and serialize equivalent functions
as the keywords. This caused issues as we would incorrectly serialize
even explicit functions as the keyword.
This also allows us to move the magic easing functions to
`EasingFunction` rather than `EasingStyleValue` which is a bit tidier
This introduces the `TextUnderlinePositionStyleValue` class, it is
possible to represent `text-underline-position` as a `StyleValueList`
but would have required ugly workarounds for either serialization or in
`ComputedProperties::text_underline_position`
These will be used for the mask-repeat property as well in an upcoming
commit, hence the more generic names. Also, this more closely matches
the names used in the spec.
This parses `anchor-size(..)` functions in CSS, but does not yet result
in a useful `Size`: we need style & layout interleaving similar to
container queries for this, since the resulting value depends on layout
results.
Not supported yet: `anchor-size()` appearing inside a `calc()` node.
Adds 4280 WPT subtest passes in `css/css-anchor-position`.
...for `text-justify: inter-character`.
We previously had this mapped in Enums.json, but the behaviour is
different: `a=b` in Enums.json keeps `a` around but makes it behave the
same as `b`. A legacy name alias is instead expected to replace `a`
with `b`, so we have to do that separately.
Because we defined `th { text-align: center }` in our UA stylesheet, it
received a higher precedence than inherited (inline) styles. Firefox
deals with this by defining a custom `text-align` value that prioritizes
any inherited value before defaulting to `text-align: center`.
We now do this as well :^)
No functional changes. The main difference is renaming the cursor enum
to match the spec term `<cursor-predefined>`, which is a bit more
verbose but clearer in meaning.
