This plugin controls a mouse/pointer from a tablet device. This
effectively hides stylus interactions and sends pointer events
instead. In other words: mouse emulation for tablets, implemented
by (remote) controlling a mouse device. This allows using a
tablet stylus as a mouse replacement without tablet limitations
from compositors or clients. Note that axis usually needed for
drawing (like pressure, tilt or distance) are no longer emitted
when this plugin is active and a mouse is connected. When no
mouse is connected, this plugin doesn't change tablet events,
thus the stylus works like a normal stylus.
