I think it is about resizing an existing Morph that is drawn with Athens
Surface? I had problems with it and had the same question. But it works well
with something like:
SomeSubclassOfMorph>>extent: aPoint
|newExtent|
newExtent := aPoint rounded.
(bounds extent closeTo: newExtent) ifTrue: [^ self].
self changed.
bounds := (bounds topLeft extent: newExtent).
surface := AthensCairoSurface extent: newExtent.
self layoutChanged.
self changed.
Now Boids fly in a resizable sky :)
