The question is how often do we need to export such a large pictures?

Else, we can always export as html. And this support well very large pictures.

Then, can we not scale the picture to fit in the maximum allowed dimensions?

Yes, pure morphic.

But rendering the above Diagramm in a morphic window and with Athens (and therefore Cairo)
