Thank you torhu, I finally managed to get something into this array! :-)
But I still dont understand if and how I can add a new ScreenElement
array to the layer map *without* setting its size in advance(because I
want to remain as generic as possible).
My original idea was to have a create_layer() function, which creates a
new layer by adding an empty array to the layer map, so I can keep
creating as many layers as I want to.
And another question: Can I modify the size of an array after I set it
