fullscreen, size and position

[Jinjinov]

While it is possible to set window size and position from C# like this:

    public void Configure(DesktopApplicationBuilder app)
    {
        app.AddComponent<App>("app");

        WebWindow webWindow = app.Services.GetService<WebWindow>();

        webWindow.Top = 0;
        webWindow.Left = 0;
        webWindow.Width = 800;
        webWindow.Height = 600;
    }

The problem is that it takes from 1 to 2 seconds for this settings to take effect.

That is why I added:

bool fullscreen int x, int y int width, int height

to all C++ and C# functions
