This demo shows very basic recording of mouse/touchpad motion
movement data under Linux and Windows.
Press a key on the keyboard to end the demo.
It requests recording of raw motion, ie. of the device itself,
in device and operating system specific distance units, not
neccessarily in screen pixels. No pointe acceleration / ballistics
should be applied to the motion. It prints cursor position, vs.
integrated raw position, vs. reported raw movement deltas for
comparison. Also mouse wheel motion on some OS + device combos.
Note that you may have to calibrate / map reported positions yourself
for any given mouse device, e.g., a 400 DPI mouse may report in different
units than a 1000 DPI mouse etc.
This functionality is not supported on Apple macOS.
