Display Scaling (again)

[bjoern]

Following up on this thread in the chat and my own post here in the forum (which is closed).

@Elias

We’ll have to add some sort of abstraction to do this or we end up with another windows dependency right in the core. That’s why it will take some thinking and can’t be done straight away. But since UI is on the horizon again it might be tackled then since we for sure will hit the same issue.

I did some more digging and came across these two:

1. A lengthy and insightful blog post by Chickensoft about display scaling on macOS and Windows and their Godot package that deals with it.
2. A rust crate that deals with display scaling on Linux, macOS and Windows.
