28b5dc6199 avfilter/vf_interlace: restore lowpass mode constants 
The documentation still mentions numerical constants in addition to textual
ones. It is also wrong to use distinct modes as flags and it disallows us to
actually use the flags field for real flags in the future.

2da5bf4c2f avfilter/interlace: add complex vertical low-pass filter 
This complex (-1 2 6 2 -1) filter slightly less reduces interlace 'twitter' but better retain detail and subjective sharpness impression compared to the linear (1 2 1) filter.
