All traversal processes are like this:
1. Traverse only elements that have this restyle hint (animation-only traversal)
RESTYLE_CSS_ANIMATIONS is stripped off from restyle hints of the elements
2. Traverse all dirty elements (normal traversal)
3. Create a SequentialTask if we have updated CSS Animations properties in
the normal traversal
4. Traverse elements that need to have updated animation style as a result of 3
(second animation-only traversal)
We will set the flag when the root node of the traversal has
has-animation-only-dirty-descendants flag or has animation restyle hints.
Also we will use this flag to detect whether we need to trigger CSS transitions
or not.
We need a scope to restore rule_node_changed that were borrowed by the closure.
This closure function will be used for animation-only restyles as well.
remove unused `use` statements in mako helpers
These are no longer needed, according to `./mach build -d` and grep.

It should be checking the value of the 'writing-mode' property, not the value of
the "writing mode" concept. The latter is influenced by other properties like
'direction' and whatnot. That was causing this code to convert inlines to
inline-blocks if they just had a different direction from their parent, which is
not correct
stylo: Bug 1349834 - Update RESTYLE_STYLE_ATTRIBUTE to sync Gecko change.
This is an interdependent patch for Bug 1349834. We remove eRestyle_SVGAttrAnimations from nsRestyleHint, so need to update the bindgen and the value of RESTYLE_STYLE_ATTRIBUTE.

Make writing-mode affect computed display
<!-- Please describe your changes on the following line: -->
The first manual test-case in #15754 passes now, but the second test-case still renders "Text" horizontally, which is apparently because of servo's experimental support for writing-mode.

A new function, cascade_with_rules, takes StrongRuleNode
and computes cascading result values with the StrongRuleNode.
This new function will be used for getting after-change-style
for CSS Transitions.

It's a bit unfortunate the use separate implementations of SpecifiedUrl for Servo
and Gecko, but they're different enough at this point that I don't think it really
makes sense to try to share everything. Splitting them out has some nice
simplifications as well.
I recognize that there's still some potential correctness issues for Servo using
the resolved URI in various places where the original URI may be the right thing,
but I've got too much on my plate to look into that for now.
