Details

After the world has been updated for a paint tick, make APZ iterate over all LayersIds, compute the transform matrix from the chrome coordinate space to the content coordinate space associated with each LayersId, and send list of LayersIds and associated matrices to the chrome process main thread. On the chrome process main thread, for each item on the list, look up a TabParent by LayersId and set the matrix on the TabParent.
