Details

See bug 1355348 comment 2. We should probably either deprecate this in Gecko or handle arrays of AnimationValues for the Servo code path.
Going through the sets of properties marked as animatable by SMIL in nsSMILCSSProperty::IsPropertyAnimatable we have the following set:

 font
 font-variant
 marker
 mask (depends on MOZ_ENABLE_MASK_AS_SHORTHAND)
 overflow
 text-decoration

I need to check if Chrome/Safari support animation of 'mask' and 'marker' but given that they seem useful to animate, and given the tendency of longhands to be promoted to shorthands we probably should support this.
