Hi all,

I would like to announce that I will start the work to unprefix CSS
Animations, Transitions and Transform. It may sounds quick to do but
it's not, there are few things to do before we can unprefix and
unleash them to the world (e.g. -webkit-perspective accept valueless
number but perspective doesn't) and we need to make few fixes to do to
make sure we are compliant with the spec while keeping the behaviour
as-is for the current unprefixed version. Also there is few
unimplemented things.

The bug is tracked here : https://bugs.webkit.org/show_bug.cgi?id=93136

In the following days I will add new bugs as blocker to this one to
track the work left to do. If you think of something missing feel free
to open a new bug and mark is as blocker for 93136. Please put a
detailed description on the bug.

I will land the work behind a feature flag
CSS_TRANSFORM_ANIMATION_TRANSITION_UNPREFIXED (I accept alternatives
on the name :), I believe three feature flags for that is overkill)
enabled by default on trunk as it is important for me to get the bots
running the code. You can turn off the feature in your release
branches up until the work is done (maybe afterwards we should even
remove the feature flag).

Thanks.
