-/// Like the CSS "px" unit, the exact physical size of this unit may vary between devices, but it
-/// should approximate a device-independent reference length. This unit corresponds to Android's
-/// "density-independent pixel" (dip), Mac OS X's "point", and Windows "device-independent pixel."
-///
-/// The relationship between DevicePixel and ScreenPx is defined by the OS. On most low-dpi
-/// screens, one ScreenPx is equal to one DevicePixel. But on high-density screens it can be
-/// some larger number. For example, by default on Apple "retina" displays, one ScreenPx equals
-/// two DevicePixels. On Android "MDPI" displays, one ScreenPx equals 1.5 device pixels.
-///
-/// The ratio between ScreenPx and DevicePixel for a given display be found by calling
-/// `servo::windowing::WindowMethods::hidpi_factor`.
