The alias is left there temporarilly and will be removed completely in a later commit where
also components/style/gecko/generated/structs_{debug|release}.rs are re-generated (they still
use the old alias).
In the next few patches we move all non-transition related code over to
using AnimatableLonghand instead of TransitionProperty. This will allow
us to re-purpose TransitionProperty to represent only properties that
can be transitioned (i.e. excluding discrete properties) as well as
simplifying the code by removing the need to deal with shorthands and
the "all" value in places that do not need to handle those values.
This file has become quite bloated lately. This commit deletes that file in
favor of a set of submodules.
The only noticeable change apart from code move, is converting deep_clone_foo
methods into a trait.
It also unifies logic related to different style rules in the same place.
There's some missing work, specially related to font-face and counter-style, but
I think this is worth landing in the meantime.
If there are multiple prefixed/non-prefixed @keyframes with the same name;
* non-prefixed rule overrides earlier rules.
* prefixed rule overrides earlier prefixed rules.

This effectively combines the discriminants of the two enums and reduces the
size of PropertyDeclaration by one word.

@keyframes anim {
from { transform: none; }
to { opacity: 0; transform: none; }
}
In above case, we have to add opacity property and value in the 'from' keyframe.
We need to create CSS animations that have empty keyframe or keyframes
which have only invalid properties or non-animatable properties to fire
animation events for such animations.
