[bug] Incorrect and inconsistent window positions

[thewh1teagle]

Describe the bug

I use tauri on v2 project on macOS
When creating new window with specific position, the position is incorrect and inconsistent comparing of doing it with global tauri.

Reproduction

Example on Rust side, it creates the window with invalid offset.

#[tauri::command]
async fn test(app_handle: AppHandle) {
  if let Some(window) = app_handle.get_webview_window("main") {
    let position = window.outer_position().unwrap();
    println!("position: {:?}", position);
    let window = WebviewWindowBuilder::new(&app_handle, "main1", WebviewUrl::App("/index.html".into()))
      .position(position.x as f64 + 30.0, position.y as f64 + 30.0) // 30px offset x+y
      .build();
  }
}

Example correct position using global tauri:

// needs  window:allow-create permission
(async () => {
    const position = await window.__TAURI__.window.getCurrent().outerPosition()
    console.log(position.x, position.y)
    new window.__TAURI__.window.Window("main1", {url: "/index.html", x: position.x + 30, y: position.y + 30})
})()

Expected behavior

The window should be created with offset of 30px on x,y

Additional context

1. Position values are inconsistent
   window.outer_position returns PhysicalPosition<i32> while WebviewWindowBuilder::new().position() expects f64
2. Using window.set_position(position); right after creating it move it to correct position

[pewsheen]

WebviewWindowBuilder::new().position() expects a LogicalPosition. Could you try offsetting the position and then convert it to the LogicalPosition to see if it's correct?

It may look like:

let mut position = window.outer_position().unwrap();
println!("Physical position: {:?}", position);
position.x += 30;
position.y += 30;
let logical_position = position.to_logical::<f64>(window.scale_factor().unwrap());
println!("Logical position: {:?}", &logical_position);
let _window =
      WebviewWindowBuilder::new(&app_handle, "main1", WebviewUrl::App("/index.html".into()))
          .position(logical_position.x as f64, logical_position.y as f64) // 30px offset x+y
          .build();
