This is more like what the IDL files specify with two different mixins,
but the inheritance structure here is slightly different for easier
maintenance. This will also allow the WebGL2 Impl to inherit from the
WebGL1 Impl as WebGL versions don't share the functions defined in the
Overloads interfaces.
The two classes now inherit from a common base MediaTrackBase, to
deduplicate the attributes that are shared between the two.
The integer ID from the container is used for each track's id
attribute.
The kind attribute is set to "main" or "translation" according to:
https://dev.w3.org/html5/html-sourcing-inband-tracks/
The label attribute is set to the human-readable name of the track, if
one is present.
The language attribute is set to a BCP 47 language tag, if one can be
parsed successfully.
We don't need all this specific logic for parsing the `transition`
property - we also now maintain `none` as such until use time which
gains us a couple extra tests
Adds support for `sibling-index()` and `sibling-count()` when parsing
`<number>` and `<integer>`. This is achieved by a new
`TreeCountingFunctionStyleValue` class which is converted within
`absolutized` to `NumberStyleValue` and `IntegerStyleValue` respectively
There are still a few kinks to work out in order to support these
everywhere, namely:
- There are some `StyleValue`s which aren't absolutized (i.e. those
which are stored within another `StyleValue` without an
`absolutize()` method.
- We don't have a way to represent this new `StyleValue` within
`{Number,Integer}OrCalculated`. This would be fixed if we were to
instead just use the `StyleValue` classes until style computation at
which time they would be absolutized into their respective
primitives (double, i64, etc) bypassing the need for *OrCalculated
entirely.
This is the final CSSStyleValue class used by the per-property test
harness, so those now actually run instead of throwing an exception on
load. 🎉
+39 WPT subtests. (Plus however many from the per-property tests finally
running.)
The two failing serialization tests are also failed by Safari in exactly
the same way, so that seems more like a spec issue. (The spec is
incomplete in quite a few places.) The failing subtest for toMatrix() is
also a spec issue: is2D is handled oddly by CSSMatrixComponent and this
subtest fails because of the `matrix` getter, which is unspecified. See
https://github.com/w3c/css-houdini-drafts/issues/1155 for details.
Equivalent to the perspective() transform function.
+34 WPT subtests, and the transformvalue-normalization test now runs to
completion instead of throwing an error - though its cases still fail
until CSSTransformValue is implemented.
This is a base type for the various transform functions.
CSSMatrixComponent's to_string() can throw exceptions, so to_string() is
implemented that way. https://github.com/w3c/fxtf-drafts/issues/611
+9 WPT subtests.
Global Privacy Control aims to be a replacement for Do Not Track. DNT
ended up not being a great solution, as it wasn't enforced by law. This
actually resulted in the DNT header serving as an extra fingerprinting
data point.
GPC is becoming enforced by law in USA states such as California and
Colorado. CA is further working on a bill which requires that browsers
implement such an opt-out preference signal (OOPS):

This patch replaces DNT with GPC and hooks up the associated settings.
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`
Generating boilerplate is nice! This also has the bonus that we're more
correct: I included all the units listed in the spec before,
(see https://drafts.css-houdini.org/css-typed-om-1/#numeric-factory )
but we're supposed to exactly include ones for the units we support:
> If an implementation supports additional CSS units that do not have a
corresponding method in the above list, but that do correspond to one
of the existing CSSNumericType values, it must additionally support
such a method, named after the unit in its defined canonical casing,
using the generic behavior defined above.
> If an implementation does not support a given unit, it must not
implement its corresponding method from the list above.
Now, our factory functions will exactly match the units we support.
The changed test result is partly the order being different, and partly
that the container-query units are no longer included as we don't
actually support them.
From the SVG spec
The value of the ‘viewBox’ attribute is a list of four numbers <min-x>,
<min-y>, <width> and <height>, separated by whitespace and/or a comma...
Currently try_parse_view_box will fail to parse the attribute if the
values are separated by commas.
This change replaces try_parse_view_box with a more correct
implementation. It will reside in the AttributeParser.cpp. This new
implementation correctly handles comma-separated viewBox values, and is
also more robust against invalid inputs.
Additionally, it adds a new test case to ensure viewBox values with
various syntax are parsed correctly and invalid values are rejected.
