-// DispatchHost hosts an IDispatch object inside a NPObject to allow scripting
-// of COM objects from a NPAPI environment. Types are automatically marshalled
-// between NPVariant and VARIANT using the functions in variant_utils.h.
-// Limitations:
-// - IDispatch methods/properties may only take arguments of type VT_VOID,
-//   VT_NULL, VT_BOOL, VT_I4, VT_R8, and VT_BSTR
-// - Multiple out parameters are not supported.
-// - IDispatch methods/properties may only return a value of type VT_EMPTY,
-//   VT_VOID, VT_NULL, VT_BOOL, VT_I4, VT_UI4, VT_R8, VT_BSTR, and VT_DISPATCH
-// - A method and property a property that takes additional arguments may not
-//   have the same identifier--the method will not be callable through
-//   DispatchHost.
