<h1>Image optimization in layers</h1>
<p>
This test exercises direct compositing of images with hardware acceleration. The visual results
using ACCELERATED_COMPOSITING and regular TOT should be identical. Running this test manually with
the correct debug options will show which elements are directly composited. See
