 When the input of `avgblur` filter is resized in time, the `avgblur` would
 keep blurring just the original area (size).

 In this example input is resized from 100x100 to 200x200 within 5 frames,
 however only 100x100 area is blurred in every frame.

 Also tried with `eval=frame` but `avgblur` doesnt seem to have the option.

 How to reproduce:
 {{{
 % ffmpeg -f lavfi -i color=size=200x200:rate=5:d=1 -i lines.png
 -filter_complex
 "[1]setpts=N/5/TB,fps=5,tpad=stop_mode=clone:stop_duration=1,scale=iw+n*20:-1:eval=frame,gblur=10,[0]overlay"
 -y out%%d.png
 }}}
