Currently, the rectangle is determined from the size of the first scene, which is not very intuitive.
It would be nice to have something explicit like excalideck printable rectangle. https://github.com/excalideck/excalideck/issues/7
This would require more sophisticated setting panel. excalideck does it well too.
At the moment, it's worse than that because the size is determined by the size of the first scene at the time a second scene is added. After that (without deleting scenes), its not possible to change the size.
