Is there something crucial missing for the M1?

Is there something crucial missing for the M1?

@ptziegler I'm a bit unsure what to do with #940 but maybe the best is to merge it early so that we get feedback soon, or?

[ptziegler]

What about #932? It would be nice to get some feedback in case I missed something for the new method.

@ptziegler good point. yes this should also be in. Have you seen the comment regarding scaled graphics. What should we do about it?

Have you seen the comment regarding scaled graphics

@azoitl Good point. I missed that one. I don't think I'll get this done and tested today, so I propose to postpone it for the M2.
