As I say, the Scratch.image does work out of the box on squeak-vm 4.0
(yes, you do need to compile the squeak plugins for scratch). See e.g.
Miriam's armel Scratch packages here http://www.miriamruiz.es/scratch/
which just rely on the distribution's squeak-vm. Would it be correct
to say the fact that Scratch worked on squeak-vm 4.0 was a happy
coincidence, and so the view from the perspective of squeak-vm is that
Scratch should either bundle its own VM, or update the image for
compatibility with the latest squeak-vm?
