The GPU compositor frees some of the cached resources when it gets
canceled during interactive editing, making the experience less smooth.
This is because when the compositor gets canceled mid-evaluation, some
of the operations won't get the chance to mark their used resources as
still in use.
To fix this, we skip the cache manager reset after canceling,
effectively only resetting when a full evaluation happens, giving all
operations the chance to keep their cached resources.
