Description Of Changes
This PR closes the bug that was reported in issue #2137 where the scale attribute was not applied to the barb components where the documentation indicated that it should. This PR adds the multiplication of the scale attribute to each component of the vector and adds a test using the attribute for barbs.
Still left to do is to potentially add this to the declarative tutorial if it is deemed necessary.
