Summary: pythoncom GetRefTypeOfImplType doesn't work

Initial Comment:
Hi,

I'm trying to get the base interface typeinfo with pythoncom.GetRefTypeOfImplType but it's always returning the typeinfo of  the IDispatch interface.

You can use the code belwo with any tlb you like to repro the problem.

Thank you for your help.

def log_base_interface( tlb ):
    n = tlb.GetTypeInfoCount()
    for i in range(n):
        iface_ti = tlb.GetTypeInfo( i )
        iface_attr = iface_ti.GetTypeAttr()

        if iface_attr[5] == pythoncom.TKIND_DISPATCH:            
                print '>>>>> Base interfaces for %s' % (iface_ti.GetDocumentation(-1)[0])
                for i in range(iface_attr[8]):
                    flags = iface_ti.GetImplTypeFlags(i)
                    refType = iface_ti.GetRefTypeInfo(iface_ti.GetRefTypeOfImplType(i))            
                    refAttr = refType.GetTypeAttr()         
                    print refType.GetDocumentation(-1)[0]

output:            
>>>>> Base interfaces for SIObject
IDispatch
>>>>> Base interfaces for Application
IDispatch
>>>>> Base interfaces for SIObjectCollection
IDispatch
>>>>> Base interfaces for LightRig
IDispatch
etc...

Message:
Without more detail, I can't see how this is broken.  Note that win32com
(win32com\client\gen_py in particular) uses this function.  Please reopen
this bug if you can provide more detail.

Message:
It isn't clear why this is broken.  Your example seems to be showing that
each of the types in that typelib have one base interface which is
IDispatch.  Do you think there is a bug in pywin32's wrapping of this
function, or that the function itself is behaving incorrectly?
