Attempted to modify "Mouse wheel scrolls", nothing happened.

Touchpad Configuration modifications are not allowed.

This is because xrdp converts the touch pad scrolling event as mouse wheel, but touch scrolling is continuous event, so xrdp send too many fake mouse wheel event to xorg. The solution is add a threshold to wheel down event or add a special handler for touch pad.

@seflerZ has solved it in neutrinolabs/xorgxrdp#234, closing.
