where and how is this controlled though?  in a default firefox window, 
the test site reports back my actual screen resolution, no matter what 
size the window is.  it seems TBB is doing some spoofing somewhere but 
it is always returning the size of the window.  1000x500 is not a screen 
resolution used anywhere, so if TBB starts with a window size of 
1000x500 we can almost be certain that it is a Tor Browser and not 
blending in with other clients
