rust-windowing/winit#1496 fixed the issue that seems to cause #128. This PR updates winit to the newest version that contains the referred winit PR.

@RagibHasin please check if this fixes the issue for you

@ArturKovacs pro tip: You can write

gelatin = { path = "./subcrates/gelatin", version = "0.4" }

so cargo run uses the local copy of the crate and publishing on crates.io still works.

Thanks @Aloso, I'll change that right away! Where does one learn such things?

So, far it is working alright with nightly, with that warning though.

I learned it just recently when reading this RFC.

@RagibHasin thank you for checking! And yeah I'll fix that warning sometime soon :D but it's not related to this issue so I'll just merge this as it is.

@Aloso hmm I just found that this is also part of the documentation I just haven't stumbled upon it. But yes, one can definitely learn a lot from just reading miscellaneous resources about Rust.
