Michael Niedermayer bca11e75fb vertical scaler with accurate rounding, some people on doom9 can see +-1 errors ...

the +-1 issue is limited to >2tap vertical filters, so bilinear upscale was unaffected
the new code is sometime faster sometimes slower but the difference is significant (~20%) so its optional and enabled with arnd=1
