GSPointOffsetFromLine(_:_:_:_:)GSPointOffsetFromLineGSPointOffsetFromLine
Like GSPointOnLine, but with the returned point offset by a certain amount onto a parallel line. So, more like the inverse of GSNearestPointOnLine.

Returns a new point offset by the given distance in the direction of the given angle in radiants.
