This is a good selling point, but...

this is what puts me off again. It takes me back to the old arcade days, and
watching kids hammer at the controls. What is insane for one person may not be
insane for another.

That said, I understand and agree that there exists an upper move velocity that
makes sense for any particular touchpad.

So I will accept two patches on this: one to set the speed limit in the MT
layer, and one which uses that limit to solve a real problem, for the touchpad
in question.

Let's end this thread here and leave unrelated people in peace.

Thanks,
Henrik
