Comment (by Krieger):
It turned out to be not easy.
After fighting with drawutils, which doesn't work with `dst` transparency
by default, i'm getting inconsistent results, will show in attachments.
Seems at the moment there's no suitable mechanism in FFmpeg for subject
feature, and modifying drawutils code is quite tricky. Any comments and
propositions are appreciated.
