Python\lib\site-packages\py2exe\build_exe.py, function
patch_python_dll_winver().

The py2exe_util extension has exports add_resource, which wraps
BeginUpdateResource, UpdateResource, and EndUpdateResource, but they are
also wrapped in pywin32 somewhere.  Stringtables are a little bit more
difficult that other resources, but see
py2exe\resources\StringTables.py.

The most important thing to remember is that these functions may
silently fail if the image file to modify is readonly.  Or something
like that.
