Well well, putting the Drawing in a Group and passing that to Platypus
makes things even worse (probably because Groups are not Flowables)!
See attached file...

I still feel this is a drawback, because it seems natural to me to
make a Drawing and include a resized version of it into a story in
order to fit the frame width or whatever...

But then, maybe my sense of what is natural differs from others'.
