[Etoys] Smaller onion skin for painting

   Yet knowing that the kids usually paints the entire drawing in one 
piece, I think that making the onion skin smaller would not solve the 
problem. It also must be considered that the XO display is very small 
and the students usually draws using the touchpad, which makes precise 
moves difficult.  Having a smaller onion skin would make even more 
difficult to draw in the XO.
    But, the idea of creating a tool where children can cut parts of a 
drawing and transform them in objects sounds very interesting. This 
would make possible to the child to paint an entire scene, and after 
that decide what is an object and what is background.
