[Pharo-project] Extent a Athens surface?

[Vanessa Peña Araya]

Hi,

I wanted to ask if it's possible to extent an Athens surface. If it 
can't be done, because as far as I understand this can't be done in 
Cairo, is it possible to simulate it at least? Is it possible to stop 
#drawDuring: and build another surface, maybe?

Thanks,
Vanessa.
