Queston about one event struct

[InnocentusLime]

I've been looking through docs for WindowEvent and found the following definiton:

ScaleFactorChanged {
    scale_factor: f64,
    new_inner_size: &'a mut PhysicalSize<u32>,
},

I have several questions

1. Why is new_inner_size a mutable reference? That seems really weird
2. Why is it a reference at all? Why not just make it a value?

If there are no reasons, I'd like to make a PR to fix that... After all it will potentially make WindowEvent 'static + Clone + Copy. Not only that. It seems like the whole Event struct will become Clone + 'static. Maybe even Copy!

There were some work to resolve that but it seems like it got stalled.
