Comment (by richardpl):

 For other boxes with overlapping frames you will need another file with
 lines and new graphhint instance.

 I don't see how to do all them in same file.

 So gray boxes would be in 1st file, red boxes in 2nd file and blue boxes
 in 3rd file, and any other boxes in next file.

 -vf graphhint=gray.txt,graphhint=red.txt,graphhint=blue.txt ...

 I also wrote luascript filter which would tehnically allow this in single
 file but script size would be even longer and parsing would be slower than
 graphhint approach.
