Subject: [PATCH] Improve preloader performance on non-accelerated platforms

Using the backface-visibility property causes 2D elements and transforms
to be elevated to a 3D context. Since the only transform being used is
rotate(Xdeg), which is a 2D transform, there is no need to incur the
extra performance penalty.
