Re: Precise scrolling for wsmouse

Greetz tech-x11,

These are useful for scrolling with precise coordinates.

The following diff adds support for HSCROLL and VSCROLL
to our wsmouse(4) and synaptics(4), where it's used to provide
much smoother two-finger and trackpoint scrolling.
The synaptics driver also gets some simplification.
I think this is much better than its previous state.

Also attached is a diff with the necessary changes to

On a -current system from today after applying the patches I get:

Otherwise I'd be interested to test - my synaptics trackpad is very sensitive to touch, anything to get it better is welcome (I've tried a number of sysctl parameters, it is usable now, but I still prefer to attach a mouse when running NetBSD on it).

Later I should make it so scrolling speed and
direction configurable in wsconsctl -m. But right now,
I should sleep.

Testing would be nice.

I have in my xorg.conf:

Section "ServerLayout"
         Identifier      "layout"
         InputDevice     "Mouse0" "CorePointer"
Section "InputDevice"
         Identifier  "Mouse0"
         Driver      "ws"
         Option "Device" "/dev/wsmouse0"
