hmm, seems so. Sorry for the noise.


I have the weighted version ready. Almost all calculations are now with 
floats the results for mean, devo,devc and corr are passed as ints so 
not much code had to be changed, the error from this should be very small.

and it is indeed very very slow (about 0.4 fps for DVD resolution on my 
P4 2.6). The differences to the unweighted were around 0.002 in my tests.

Patch is here:
