@bjorn Just to be sure I am understanding this correctly. What is happening is that the object's position is placed using the top-left corner as a reference, but besides that the inversion of the Y axis is working properly, right?

Well, in my opinion, that seems a problem that needs to be solved before merging the whole functionality of this PR, because it may lead to some confusion to the users if not. But depending on the approach, I think it could even be a completelly different functionality.

Do you think users may be interested in choosing the corner which the object is aligned? Because in that case, it could even be a different customizable option, implemented separately from this one. I'm not sure about if this has any utility for users, but if we are going to do the work, we could assess if it's worth doing it.

Anyway, in my opinion, I think we should work on changing the objects corner-alignment before merging it. I can work on this, but I'll need some time to familiarize myself with the code better before doing any changes. Is it possible to see a class diagram or something similar to understand better of the code is structured?
