<h1>Image optimisation in layers</h1>

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
