Bug 20770 – Make transform animation behavior match spec

• Status: RESOLVED
• Resolution: FIXED
• Component: CSS

[Chris Marrin]

The latest version of the CSS Animation and CSS Transition specs give rules for how to handle animation between transform lists. Basically, if the lists match in size and the corresponding operators in the list match, animation is done on an operation-by-operation basis. Otherwise, the lists are reduced to and AffineTransform and those are animated as described in https://bugs.webkit.org/show_bug.cgi?id=20667.
