Rebaselined compositing/visibility/visibility-image-layers.html

The CSS visibility property was not being properly obeyed by many
specialized layer types in the accelerated compositor. The root of
the problem was that drawsContent and contentsVisible flags were
not properly propagated into the compositor. This patch removes
the drawsContent() callback, and instead makes sure that
drawsContent and contentsVisible are "pushed" through the
accelerated compositor.
