Here we define each of the three individual animations that
we will be using to have our 3D rotation effect. The first
animation will perform a full rotation on the x-axis, we'll
use that on the whole set of objects. The second and third
animations will perform a full rotation on the y-axis in
opposite directions, alternating directions between rows.
Note that you currently have to specify an intermediate step
for rotations even when you are using individual transformation
constructs.

<p>This is a test for <a href="https://bugs.webkit.org/show_bug.cgi?id=39139">Bug 39139: Pages
that use hardware acceleration don't repaint after waking computer from sleep</a>. To test, put
your computer to sleep (or "Standby", as Windows calls it). When you wake your computer up, the
animation below should still be running.</p>
