This seems similar to what I tried in https://bugs.webkit.org/attachment.cgi?id=327061&action=review

OK, I thought what I fixed in comment 5 was again due to rotating unified build but it seems it was actually this change. I guess several cleanup changes in this patch could be handled outside to facilitate review.

This seems wrong since numNodes is the size of the whole scrolling state tree not of the child list. I guess that's why I had tried to encode the child index in https://bugs.webkit.org/attachment.cgi?id=327061&action=review

This is the patch rebased on top of bug 192398, but I think my comment 11 regarding RemoteScrollingCoordinatorTransaction still holds.

Sorry for the duplicate patch; let's work on your version.

OK, my patch is from one year ago though so probably we could just work from your version. BTW, I extracted the minor refactoring parts in bug 192398.
