This is a temporary step needed to support Gecko's getKeyframes() API
until we implement bug 1391537. It only takes effect when
a ComputedValues object is supplied and only for longhand declarations.
stylo: Remove a lot of the restyle damage related complexity.
The only reason why we had the `existing_style_for_style_damage` bit is to apply
some optimizations that we don't have anymore.
I still want to reintroduce a few of them, at least for the non-eager
pseudo-element case... But I think I won't need this at all.
This allows us to remove a fair amount of Gecko code too.

The only reason why we had the `existing_style_for_style_damage` bit is to apply
some optimizations that we don't have anymore.
I still want to reintroduce a few of them, at least for the non-eager
pseudo-element case... But I think I won't need this at all.
This allows us to remove a fair amount of Gecko code too.
Let's see the example: "rotatex(360deg)" to "none".
While we do interpolation between "rotatex" and "none", the original code
path is:
1. Build an identity transform for none and always use (0, 0, 1) as the
direction vector, i.e. Rotate(0, 0, 1, 0deg).
2. Do interpolation between rotatex (i.e. Rotate(1, 0, 0, 360deg)) and
Rotate(0, 0, 1, 0deg). Because their direction vectors are different,
so we do matrix decomposition/interpolation/recomposition on both
functions. The problem is, matrix decomposition makes the 360deg
disappear, so it looks like "rotatex(0deg)".
3. Obviously, we are trying to interpolate from rotatex(0deg) to none, so
the interpolated matrix is always an identity matrix.
I think rotatex, rotatey, and rotatez are special cases which should
really rotate according to the angle, so we should build the identity
transform for them according to the normalized direction vector, and so we do
interpolation on the angle, instead of converting them into matrix.
Replacing build_identity_transform_list() with
add_weighted_transform_lists(list, list, 0, 0) might be another solution;
However, I didn't do that because build_identity_transform_list() is
much simpler.
End TreeBuilder's reliance on DOM.

style: Less messy namespace handling.
This PR accounts for the fact that the namespace table is only needed in
`NestedRuleParser`, and only for style rules, in order to simplify the setup and

style: Replicate the list of stylesheets on the layout thread.
This is a patch that unifies a bit how Gecko and Stylo stylesheets work, in
order to be able to eventually move the stylesheets into the stylist, and be
able to incrementally update the invalidation map.
This is on top of #18113

We need to use enum instead of Either since we can't interpolate stroke-* between
unitless length and unit length(e.g. '5' -> '10px').
This coomit make following:
* Introduce SVGLengthOrPercentageOrNumber on computed and specified values.
* Make SVGLengthOrPercentageOrNumber animatable.
* Make stroke-dasharray not-accumulate.
Improve containing block creation for position:absolute flows
Instead of only promoting flows with positioned fragments to containing
blocks, also do this for flows which have the transform, perspective or
filter properties set. This is what the spec requires and also fixes
some failing tests. It will allow us to stop creating stacking contexts
for overflow:hidden and overflow:scroll flows.
Fixes#18091.
