GEGL would prefer to be accurate rather than fast, and when trading
quality for speed - making it optional. It could make sense to allow
toggling a fast path in gegl:gaussian-blur. For now though it could
make sense to keep the alternate gaussian blur in the workshop where
it isn't compiled by default but still kept available.
