Sculpt for slides presentation

Hello Norman

Thanks for the inspiring Talk about the new Sculpt version. During this talk, you switched between the leitzentrale, runtime and slides layers.

I tried to do the same, but failed. I can show a PDF using pkg/pdf_view by routing it - for example - to "themed wm" or "background". How can I use the "slides" layer and how do I can make sure the PDF is shown with "optimal" zoom level (page with/height)? How can I toggle the slides layer on and off?

Thanks, Roman
