[webkit-dev] removing vendor prefix from CSS animations, transitions

A few months ago the CSS WG approved unprefixing Animations,
Transitions and Transforms implementations. By now IE, Firefox and
Opera have released betas or previews with unprefixed versions of at
least some of those.

Simon Fraser already commented that Transforms require more work
before un-prefixing (https://bugs.webkit.org/show_bug.cgi?id=93136):
> We need to make a bunch of behavior changes before we can drop prefixes on transforms. From memory:
> 1. Require units on perpective (function and property)
> 2. Implement transform function matching for animation according to the spec
> 3. Implement the 3D rendering context stuff properly (layer intersection)
> 4. Change background-attachment:fixed behavior.
> 5. Probably more.

How about Animations and Transitions, is there a reason for me to not
send patches that enable the unprefixed properties and events in those
specs at this point?
