Right now when we create layers-free WR transaction, we put together a tree of scroll data information [1] to send over to APZ. This scroll data includes things that APZ needs to know such as the scroll metadata for a particular scrollable frame. One of the things currently missing from this data structure is the transform information. We need to create WebRenderLayerScrollData nodes with transform/perspective information so that on the compositor side APZ knows what things are transformed and can adjust coordinates accordingly.
