========= PLEASE KEEP THIS IN SYNC WITH test_animations.html =========
This test mimicks the content of test_animations.html but performs tests
specific to animations that run on the compositor thread since they require
special (asynchronous) handling. Furthermore, these tests check that
animations that are expected to run on the compositor thread, are actually
doing so.
If you are making changes to this file or to test_animations.html, please
try to keep them consistent where appropriate.
