Dzmitry Malyshau 3aa374797c Bug 1525641 - Revise WR backface visibility semantics, separate picture and primitive logic r=gw ... This changes our backface visibility semantics to a slightly more complex rule, as described by Matt (and reinterpret by me in the context of WR) in bug 1525641 during our work week. We are now propagating is_backface_visible to pictures and evaluate it in the context of the local transform for a picture if it's outside of preserve-3d context. We also refactor get_relative_transform() a bit. Note: this fixes all of the existing backface-visibility bugs: 1525641, 1546110, 1546818 It also passes the Wrench tests, but the try push is still pending for surprises.
