How to draw a Morph with Athens?

At the moment i draw Morphs with Athens by copying how it is done in AthensDemoMorph:

- adding a surface variable,
- initializing an AthensCairoSurface,
- getting an athens canvas by calling: surface drawDuring: [:canvas | ]
- …

Is there already a more straightforward possibility in the meantime?
Also the way it is done in the AthensDemoMorph, when i save and quit an image with such a Morph open, there is a drawing error (red rectangle with yellow cross), once i restart the image.

BTW, i really like drawing with Athens!

u you u no draw morphs by athens :)

- use AthensWrapMorph.

put as many submorphs into it, and they all will be drawn via Athens.

eventually, the need in wrap morph will disappear once WorldMorph (the root of all morphs) start using Athens directly.

Ok, thank you, that's nice.
What is the intended use - subclass AthensWrapMorph instead of Morph for my own Morphs, or make my Morphs subclasses of Morph as usual and always create a AthensWrapMorph and then add them as submorphs?

the second choice.
This way when we swicth to athens you will have nothing to do.
