TInvokeableVariantType is a TCustomVariantType descendent which implements the TCustomVariantType.DispInvoke method. It translates the DispInvoke" method to calls to one or more of the four methods of IVarInvokeable: DoFunction or DoProcedure for method calls (DISPATCH_METHOD) and GetProperty for property reading (DISPATCH_PROPERTYGET) or SetProperty for property writing (DISPATCH_PROPERTYSET). Other combinations are possible. It has empty stubs for these methods, which must be implemented in a descendent that is used to describe a custom variant.
