renderTimeout
The default timeout used for methods that wait for a render to settle.
If not set, this defaults to a 1 second. The thought here is that we're never waiting for some 10 second real-time animation to finish, but rather we're waiting for the Kotter engine to resolve its current event loop, which should barely take milliseconds.
You can set this to Duration.INFINITE if you want to disable timeouts for your test.
