filterUnits defines the coordinate system for the filter attributes x, y, width and height. If filterUnits="userSpaceOnUse", all attributes represent values in the current user coordinate system that is in place at the time when the filter is referenced.

If filterUnits="objectBoundingBox", then all attributes represent fractions or percentages of the bounding box on the referencing element.

If attribute filterUnits is not specified, then the effect is the same as specifying a value of objectBoundingBox.
