Is there any reason, then, not to always put -filter_complex as the first 
parameters of the command line? The Synopsis line in the docs shows global 
options first but most of the doc examples don't.

ffmpeg -i video.mkv -i image.png -filter_complex '[0:v][1:v]overlay[out]' 
-map '[out]' out.mkv"

Or is there another reason for listing inputs, then -filter_complex, then
