Enable or disable double-tapping. Change sensitivities. Enable or
disable scrolling and change the scroll rate.
Of course, my diffs would only help folks with USB connected synaptics
pads -- as ours are. They don't do anything for PS/2 connected pads.
But someone else might have similar changes for those.
