     // For example
     // Suppose:
     //  - No size scaling.
     //  - Client is a HiDPI Chromebook device.
     //  - Host is running on a HiDPI Windows device.
     // With the configuration above, the client will send the logical touch
     // size to the host, therefore it will be smaller on the host.
     // This is because a HiDPI Chromebook device (e.g. Pixel) has 2 by 2
     // physical pixel mapped to a logical pixel.
     // With scaling, the size would be the same.
