I think you can update computeFilterOperations to avoid adding the clients, but I think that we still need a real client. For example, what happens if the shaders are loaded when the animation is already supposed to be running? My expectation would be that the animation will load the shaders and still be able to run. At least that's what happens in the software pipeline.

Also, this problem might be a good question for the w3c CSS group: Should the navigator postpone the start of the filter animations until the shaders are loaded? I think shaders are the first to have this problem.
