implementation

Here's an implementation that handles absolute movement events.

It can operate in two modes:

a) touchpad mode. The absolute x- and y-coordinates are compared with previous
values and the difference is reported as relational movements. This is for
touchpads.

b) normal mode. The absolute x- and y-coordinates are reported as absolute
movements. This is for touchscreens.

There's also support for tapping, so that a tap on the touchpad causes a button
click.
