How do I resize to the actual dimensions? I mean at some point I have to
set them.
Will mat.resize(rows, cols) work?

That sounds like a good approach to me. I just want to know whether it
is useful to others as well. I don't like to extend the API with a
feature that nobody cares about. It may even lead to misunderstandings.
But the above it should be pretty convenient.
