Description

In https://bugzilla.mozilla.org/show_bug.cgi?id=1465792 it appears that webrender is getting pegged by a progress bar with an animated linear-gradient, where the animation is just the offset of the gradient being moved.

Not sure how high priority this is, it sounds like non-trivial gecko work may also be required.

Contributor guide

Research direction
Examine the current gradient implementation in shader code and understand how static gradient properties are handled. Then design a way to make start/end points dynamic using DynamicProperties, referencing the linked bug report for context on performance issues.
