Are you sure? (Or alternatively: maybe I don't understand what you mean?)

By "clear operation" I assume you're referring to the call in Window.java `gg2dfillRect`. This clear logic has existed since 2009, so I'm reluctant to remove it. (And if we remove it: we can just remove the entire `paint(Graphics)` method, because that's the only reason it's overridden, right?)

Here's a screenshot of the code in question & a little git annotation:

If you still want me to try to migrate this logic: can you give me an example of which classes you'd recommend trying to move it to?
