As part of the threaded animation resolution work (bug 250970), we will need to be able to identify cases where "filter" values cannot be interpolated because it will be both difficult to implement animation of mis-matching filter lists using the CAPresentationModifier SPI and also because it doesn't make much sense to run an animation in the UIProcess for values that will not continuously change. The logic that determines whether two "filter" values can be interpolated is private to CSSPropertyAnimation as it stands, it would be better to have it exposed on FilterOperations.
