1429301 - Implement offset-rotate for motion path

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, enhancement, P3)

Description

[Boris Chiou [:boris]]

We implement offset-rotate [1] in this bug. offset-rotate defines the orientation of the box while positioning along the offset-path.

offset-rotate is an animatable property, but for simplicity, we could make it non-animatable for now.

Note:
The computed value of offset-rotate doesn't need to store "reverse" because "reverse <deg>" is immediately converted to "auto <180+deg>", so the interpolation and property equality code never needs to consider "reverse".

The docs are finished for Motion Path, for now. See https://github.com/mdn/sprints/issues/1961#issuecomment-526318438 for the specifics of what I've done.
