RenderableLayer - use a Set instead of ArrayList?

[Joao Fonseca]

Hi,

Shouldn't RenderableLayer use a Set<Renderable> to hold all its renderables, instead of an ArrayList?

The benefit would be that adding the same Renderable many times wouldn't cause multiple instances to be kept in memory.

With the ArrayList, we have to keep track of which Renderable have been added to the layer, to prevent multiple instances.

In my case, I have shapes that are added or removed in response to certain events. When an "ADD" event arrives, I have to check if the shape is already there.
