--Updated HWUI holepunch logic for SurfaceView to also apply the stretch to the hole punch --Updated RenderNode callbacks to also include an offset from the ancestor RenderNode that also has a stretch configured on it --Added new test activity to verify hole punch logic Bug: 179047472 Test: manual Change-Id: Ibbaf8248a31839ba9dc352ecb9fef54e1276918e
