--mouse-sensitivity or -s introduces a dead range.

[Gibitwit]

I was excited to see that --mouse-sensitivity now works. But it adds a hefty dead range to mouse movement. The view will not move at all without a good amount of movement of the mouse in a short time. This makes --mouse-sensitivity option useless. I suppose it does not actually scale mouse tracking but throws out counts instead.

Please eliminate the dead range.
