             * DISPPARAMs provides two different ways to pass arguments.
             *
             * Arguments can be passed as a linear list with all arguments
             * specified to a certain position (positional) or the position of
             * an argument can be passed via the rgdispidNamedArgs array
             * (named).
             *
             * pDispParams.rgvarg (length in pDispParams.cArgs) contains all
             * arguments (named + position based)
             *
             * pDispParams.rgdispidNamedArgs (length in pDispParams.cNamedArgs)
             * contains the named parameters as DISPIDs - the DISPIDs are the
             * target index in the method signature (zero based).
             *
             * Each entry in pDispParams.rgvarg is either position based or name
             * based and the position bases arguments are passed in reverse
             * order, so getting this:
             *
             * rgvarg = ["arg1", "arg2", "arg3", "arg4", "arg5"]
             * rgdispidNamedArgs = [3, 4]
             *
             * Would lead to this paramater array in the handler:
             *
             * ["arg5", "arg4", "arg3", "arg1", "arg2"]
             *
