    3030== Device scale ==
    31 Device scale is a property of the physical display that the web content is being rendered into.  This could be a monitor, projector, print media, etc.  The device scale can change for a given Page, for instance if the window containing the Page is moved to a different monitor or if the user switches from using a monitor to using a projector.  The device scale typically does not change as a result of the user interacting with the web page.  When the device scale changes, a browser implementation may wish to re-rasterize the content at the new scale in order to render vector content more sharply.  The size of the viewport and the layout of the page do not change if the device scale factor changes.  Web pages may use window.devicePixelRatio and CSS media queries to provide different content, such as higher-resolution image assets, for high-DPI devices.
