Re: [csswg-drafts] [css-animation] Motion Blur (#3837)

That looks good to me. Other key points from the discussion, as I understand it:

- The property should have no side effects; it doesn't force a compositor layer on its own & doesn't change rendering for non-moving elements.
- User agents would have some flexibility in deciding which types of movement _do_ trigger motion blur (for `auto` but also for `blur`). It could include scrolling motions as well as transforms and motion path.  It wouldn't normally include changes that are implemented with repaints on each frame.
- The exact blurring algorithms would be implementation dependent. When deciding which motions trigger blur, user agents should make reasonable trade-offs to create an overall smooth animation.
- Adding this property doesn't prevent CSS adding directional blurring to `filter` (etc.) for more direct author control of smear/swipe effects, in the future.

Next step would be to get feedback from implementers on how easy/hard this would be to implement & whether they're likely to do so if it gets spec'd.
