Description Said Abou-Hallawa 2023-05-13 07:11:35 PDT

This will be needed when caching the FilterResults in GPUProcess. We need to identify the modified FilterEffects so we can clear their FilterImages. They will be regenerated when the filtered ImageBuffer is displayed.

The FilterEffect::operator==() will be virtual and will be overridden by all the superclasses. All the properties of the superclass and the properties of FilterEffect will be compared for equality.
