If we are interpolating between a dimension and a percentage value and
the dimension component is 0, we now return a percentage value rather
than a `calc()` value.
This removes the AnimationRefresh argument from `collect_animation_into`
which was added in a9b8840 - it's only effect was disallowing
`UseInitial`s within keyframes when we were doing animated style
updates which I believe is unintentional.
Gains us 214 WPT tests.
The transform of each paintable was being applied multiple times due to
the recursive nature of the hit testing methods. Previously it used
combined_css_transform to transform the position, and then it would pass
that position to children, which would then apply combined_css_transform
again, and so on.
PaintableBoxes are also not hit tested anymore when having a stacking
context. A similar check is done in PaintableWithLines, but it was
missing from PaintableBox. Without this check some elements can get
returned multiple times from a hit test.
StackingContexts with zero opacity will now also get hit tested, as it
should have been before.
- Omit calcs that are resolved to `0px` from the serialized value
- Allow CSV to be the 'Z' component in interpolated value.
- Allow calcs with mixed percentages in the first two arguments.
To achieve the third item above the concept of a "special" value parsing
context has been added - this will also be useful for instance for
different arguments of color functions having different contexts.
Gains us 23 WPT tests
Previously, when serializing an angle value, we would always convert it
to degrees. We now canonicalize the angle value only when serializing
its computed value.
This allows us to disable test output, which performs expensive assert
tracking. This was making our imported tests run significantly slower
than tests run via `WPT.sh`.
Formatting the output ourselves also allows us to remove unnecessary
information from the test output.
This commit also rebaselines all existing imported WPT tests to follow
the new format.
