public final class VectorUtil

extends SWIHandler

This class represents the VectorUtil module which is used by Jonathan Marten's Draw Plus, Vector, GridPro etc. It is not a RISC OS ROM module but until we can handle loading RISC OS modules we need to reimplement this one in Java and pretend it is.
