Although the ProxyObject by definition exposes a IDispatch, the methods are not callable via the Proxy.
…etIDsOfNames) dispIDs can be queried via GetIDsOfNames at runtime or retrieved from the typelibrary when bindings are generated. Using the dispID eliminates one additional call into native environment. It was also observed, that runtime reflection sometimes retrieves wrong values (toString on IHTMLDocument2), so using a previously retrieved value seems to be saver.

This looks ok to me, maybe @lgoldstein could help with a more thorough CR, I don't understand half the code ;) |

The ProxyObject implements several base interfaces directly, but the methods were not correctly handled. This pull modifies the InvocationHandler part to select methods based on declaration interface with direct method invocation, instead of manually redirecting each method.
The second part adds more robustness (and speed as sideeffect) to ProxyObject by using dispIDs if they are available, making reflection via GetIDsByName unnessary.
