[Rounded Corner] Handle ContainerLayer correctly.
Previously we always use the source bounds of the child layer, this is correct
until two layers overlapped and form the hierachical structure. In this case we
need to use the source bounds of the parent, however, source bounds on
ContainerLayer usually doesn't make sense, in that case we need to use the
child source bounds.
