Comment 8 for bug 1539009

Manual test case using only mir-demos:

0. Get a high quality high resolution mouse.
1. Add this to your kernel command line and reboot: usbhid.mousepoll=1
2. Start the server: $ sudo mir_demo_server --mouse-acceleration=none --vt=1
3. Start the client: $ sudo env MIR_CLIENT_INPUT_RECEIVER_REPORT=log mir_demo_client_egltriangle
4. Move the window into the middle of the screen.
5. Swipe the mouse across the screen (and over the window) very quickly.
6. Now look at the client's input receiver report closely...

Verify: Changes in the 'x=' values should match the 'dx=' values fairly closely.
