[Bf-python] Possible bug with transformations

[Tron Thomas]

Yeah, I'm not sure that I made it clear in my original post what I was 
trying to accomplish, so it is not surprising there might have been some 
confusion.  I suspect this resize behavior for the vector is different 
from what was in version 2.37, because my script was working fine in 
that version, and now I'm having to make changes.  At least now I have 
an idea as to why things are not working as expected.
