    //Get the displays
    auto displays = GetDisplays();

    //Create window
    auto window = CreateWindow("Ultra Engine", 0, 0, 800, 600, displays[0]);

    //Create user interface
    auto ui = CreateInterface(window);

    //Create a pixmap
    auto pixmap = CreatePixmap(512,512);
    pixmap->Fill(Rgba(0, 0, 0, 255));

    //Show the pixmap
    ui->root->SetPixmap(pixmap);

    auto button = CreateButton("Modify Pixmap", 10, 10, 100, 30, ui->root);
