In bug 1449068 and bug 1449087, we are moving those rules to be backed by the Servo side data struct. To minimize the changes there so that we can unblock other works as soon as possible, I'm only doing conservative changes that converting values to nsCSSValue to feed Gecko is not changed. But that may have some performance impact since nsCSSValue conversion can be expensive for some data. Also having to convert Rust data to nsCSSValue just for converting them to final form actually consumed by Gecko code seems to be wasteful. We should remove the nsCSSValue intermediate layer and try to have Gecko code fetch needed data from Servo side directly.
