Reproduction steps

Hey! I'm new to Zed and wanted to learn gpui by going through the examples, but I'm running into compilation errors.

I tried running the input.rs example and got two errors:

 - line.paint() is being called with 6 arguments but it only takes 4 now
 - window.focus() is being called with 2 arguments but only needs 1

Looks like the API changed but the examples weren't updated. I haven't checked the other examples yet but there might be more with similar issues.

I'm happy to go through them and submit a PR to fix these up if that would be helpful? Just wanted to check first if anyone's already working on this or if there's something I'm
missing.

Thanks!

Current vs. Expected behavior

Errors are all fixed when we say as complier says , which seems like the the function defination changed
