We should only draw the sourceImage is the whole filter chain is Noop (no-operation). At least This will save us from duplicating the sourceImage for SourceGraphic. Are Noop filters common? Yes some pages may initially display their images blurred then decrease the blur radius to zero through animation. So every time these images are displayed after that will be displayed as filtered images even the applied filter has no effect.
