style: Forbid accessing the length and percentage parts of a LengthPercentage separately.
This is just not a thing you can do if you have min() / max() / etc, as the min
/ max value may depend on the percentage basis.

style: Update the expected direction vector of rotate property in wpt.
For interpolations with the primitive rotate3d(), the direction vectors of
the transform functions get normalized first. This should also be applied to
rotate property.

style: Treat 3d translate/scale as 2d if the value can be expressed as 2d.
For the individual transform properties if they spec a value that can be
expressed as 2d we treat as 2d and serialize accordingly.

We drop Translate::Translate and Scale::Scale, and then rename
Translate::Translate3D as Translate::Translate, Scale::Scale3D as
Scale::Scale. So now we use Translate::Translate to represent 2d and 3d
translation, and Scale::Scale to represent 2d and 3d scale. There is no
difference between 2d and 3d translate/scale in Gecko because we always
convert them into 3d format to layers (on the compositor thread), so this
change makes things simpler.

3034d66eef style: Use cbindgen to back CSS transforms.
This avoids the expensive conversion, and cleans up a bunch.

Further cleanup is possible, just not done yet to avoid growing the patch even
more.

c16e88d229 style: Remove Options from TransformOperation.
This may or may not be part of the plan to get rid of nsCSSValue ;)

Option is not usable via FFI, and they should not be needed (we should be
following the shortest serialization principle instead). These patches also do
that, which matches the other transform properties. I think that slight change
is fine, if we can make it work, and consistent with other properties.

Alternative is adding more TransformOperation variants or such, which I rather
not do.

7d01114cbf style: Add a Zero trait that doesn't require Add, and use it in place of num_traits and IsZeroLength.
Use it to be consistent in InsetRect serialization and storage between Servo and
Gecko.

daf1f02feb style: Rename LengthOrPercentage to LengthPercentage.
It does not represent `<length> | <percentage>`, but `<length-percentage>`, so
`LengthOrPercentage` is not the right name.

This patch is totally autogenerated using:

rg 'LengthOrPercentage' servo | cut -d : -f 1 | sort | uniq > files
for file in $(cat files); do sed -i "s#LengthOrPercentage#LengthPercentage#g" $file; done

ca503b4908 style: Simplify computed::LengthOrPercentage and friends.
This is a first step to share LengthOrPercentage representation between Rust and
Gecko.

We need to preserve whether the value came from a calc() expression, for now at
least, since we do different things depending on whether we're calc or not right
now. See https://github.com/w3c/csswg-drafts/issues/3482 and dependent bugs for
example.

That means that the gecko conversion code needs to handle calc() in a bit of an
awkward way until I change it to not be needed (patches for that incoming in the
next few weeks I hope).

I need to add a hack to exclude other things from the PartialEq implementation
because the new conversion code is less lossy than the old one, and we relied on
the lousiness in AnimationValue comparison (in order to start transitions and
such, in [1] for example).

I expect to remove that manual PartialEq implementation as soon as I'm done with
the conversion.

The less lossy conversion does fix a few serialization bugs for animation values
though, like not loosing 0% values in calc() when interpolating lengths and
percentages, see the two modified tests:

 * property-types.js
 * test_animation_properties.html

c81e1d82d5 style: Expand the mako code of Matrix3D and move them into transform.rs.
Although the methods of Matrix3D in animated_properties.mako.rs could be
simplified by mako, it's a little bit hard to read because they are far
from the usage and definition. Therefore, we move them to the definition of
computed::Matrix3D and expand the mako.

7f3b23126a style: Implement ComputeSquaredDistance for individual transforms.
We manually implement ComputeSquaredDistance for Translate, Rotate, and
Scale because we have to handle mismatch cases, and actually we don't
need to implement it for specified types.

e83f5629ff style: Move the animation code of transform into a different file.
Basically, most of the animation code of transform don't need mako, so
we could move them into values/animated/transform.rs.

However, we still use mako to generate some code to make the methods of
Matrix3D simpler, so I still leave them in animated_properties.mako.rs.
