decoded results of software scalling with bilinear

I saw some saw artifacts when doing decoding->downscaling->display. 
So I tried different VA_FILTER_SCALING_XXXX flags in vaPutSurface, but I got
the same results.
I also tried the software pipeline in gstreamer, I used ffvideoscale's Bilinear and bicubic method, no saw artifacts occured.

This was fixed years ago.
