Andy McFadden ea379fce18 Consolidate wireframe data validation
Some tests were duplicated between VisWireframe and the code that
consumed the data.  We now expose the Validate function as a public
interface, and invoke it from WireframeObject.  Failed validation
results in a null object being returned, which was previously allowed
but not actually checked for.
