This will make it easier for themes to style radio buttons
differently from check buttons, since out CSS does not have
:has().
The concrete desire here is to use a different outline for
the focus rectangle.
Update affected tests.
Fixes: #6936
The context->variables field is expected by the resolve code to be
the keyframe variables. That code takes the style variables from
context->style anyway, so no need to pass them as context->variables
too. And crucially, the lookup code treats the keyframes variables
differently to the style variables, since it doesn't expect the
hierarchical structure that comes from parent styles. This change
fixes infinite recursion in variable lookup with css like
:root {
--a: var(--b);
}
.foo {
--b: var(--a);
color: var(--a);
}
Test included.
Fixes: #6881
This regression was introduced in aeac2b54.
We need percentage values to stay non-computed, since we otherwise
fail to compute relative font sizes properly. But we want percentages
not to stick around in relative colors, so tweak things to be more
aggressive with simplication when creating relative color values.
Update affected tests.
Fixes: #6868
If the color was specified using the legacy rgb(), we must accept
values in the range [0, 255]. But when serializing it as
color(srgb...), we must scale those values to [0, 1].
Update the one affected test.
When the color property is inherited, don't resolve the inherited
value to find the used value, just inherit the used value of the
parent style.
This is what browsers do, even though the spec says something else.
Update the currentcolor4 style test to reflect these changes.
Fixes: #6833
These tests check various situations with inheritance and
currentColor. In particular the caret-color test was not
working correctly before we handled used values explicitly.
Parse things like "in hsl hue longer". For details, see the
CSS Images Module Level 4, https://www.w3.org/TR/css-images-4.
This commit fixes preexisting brokenness in conic-gradient parsing
and printing as well, and includes the relevant test changes.
Tests included.
Gradient interpolation color spaces aren't supported for
rendering yet.

The code parsing interpolation methods hadn't learned about
or latest color space additions. While we're at it, improve
the error reporting a bit.
Tests included.
Currently we only have sRGB, so it's a bit redundant, but we'll need this
for color-mix()
Once we have more color spaces, they should be added here (presumably the
enum would be in GDK instead, and instead of GdkRGBA these colors would
have a GdkColor.
Make calc() work in colors too, since we need to support degrees for hsl()
hue anyway and it goes through the same machinery. Make that work for
legacy syntax too, matching the spec.
Ignore missing components/none for now.
Ignore gdk_rgba_parser_parse(), that's also used outside css.
Warn for uses of @name colors, since these should be replaced with
CSS variables and custom properties. We don't issue deprecation
warnings for @define-color uses, since we may want to keep these
around in theme CSS for a while, for backwards compatibility.
Update all affected tests.
Implement the functions described in the "Mathematical
Expressions" section of the "CSS Values and Units Module
Level 4" spec, https://www.w3.org/TR/css-values-4/.
Beyond calc(), which we already had, this includes
min(), max(), clamp(),
round(), rem(), mod(),
sin(), cos(), tan(), asin(), acos(), atan(), atan2(),
pow(), sqrt(), hypot(), log(), exp(),
abs(), sign(),
e, pi, infinity and NaN.
Some tests included.
We'll need this to support variables in @keyframes, since styles will
need to combine their own variables and the ones from the keyframes.
See the next commit, this one is split out to avoid a huge diff.
