[Cuis-dev] Clipping operation

[Hilaire Fernandes]

Ah Ah, I have a slightly different approach.

I created a ClipperMorph kind of LayoutMorph then create one class side 
method.

clip: aMorphToClip
     ^ self newColumn
         addMorphUseAll: aMorphToClip;
         yourself

and the needed clipsLastMorph method, that's all.

As you mentioned, the added morphs are clipped.
Problem solved.
