`width` & `height` are not accessible as globals across imported Python modules in the same directory

Unlike in Processing tabs that exist in the same folder, different Python modules in the same directory does not share width and height information. width and height have to be imported to the Class constructor for now as a workaround.

Example:
noc-2-mewnala-port > chapter2 > Example_2_6_Attraction

• width and height are declared in Example_2_6_Attraction.py setup
• Attractor.py and Mover.py are also trying to access width and height
  Note that there is no error anyway if we try to run the sketch without providing width and height to the Classes, but it isn't exposed to modules outside the one that has size(width, height) in the setup

Reproduisez le comportement dans noc-2-mewnala-port/chapter2/Example_2_6_Attraction, où setup définit width et height tandis que Attractor.py et Mover.py y accèdent. Commencez par suivre la manière dont les modules du même répertoire reçoivent l’état de Processing ; c’est terminé lorsque ces modules peuvent accéder à width et height sans les transmettre à leurs constructeurs de classe.
