// Error object. Declared here (with its real msscript.ocx IID) so the type
// library describes it. RegisterTypeLib then registers an oleautomation
// marshaler for {70841C78-...}, which lets the strongly-typed IScriptError /
// Error interface be marshaled across COM apartments (e.g. an STA-created
// object consumed from a host running on an MTA thread). Members are listed in
// the exact vtable order implemented by CTScriptError.
