*Summary*: WebKitCSSMatrix has been available for years in WebKit based
browsers and has seen widespread usage on the web. This feature is
currently available in Chrome, Safari and Edge. Mike Taylor has been
working on standardizing the feature and it is being implemented in Gecko
to improve web compatibility.

*Bug*: https://bugzilla.mozilla.org/show_bug.cgi?id=717722

*Link to standard*:

It seems to me this is important to have behind a preference that is
specific to new webkit-prefixed features, given the compatibility
risks of shipping support for some but not all webkit-prefixed
features.

(It's possible it could be the same preference as other new
webkit-prefixed CSS features.)

This is probably a good idea, given the (frequent) interdependency
between WebKitCSSMatrix and webkitTransform:
