Comment (by warp):

 I have a feeling that this is more likely to be a Gen-2 issue, as the
 current touchpads simply don't offer the range of pressure sensing needed
 to do this by anything other then timing.

 Specificly, normal touching pressure generally maxes out the pressure
 sensor, making it hard to tell brief firm taps from other things.

 There are some things we could try, purely timing related testing,
 requiring a firm tap or a tap by fingernail and detecting based on a very
 brief switch to PT mode (a very firm push, or a touch with the fingernail,
 may trigger this reliable enough, though we wouldn't have dragging at
 all), that sort of thing.

 Aside from the PT switch detection, this is all in xf86-input-evdev
 programming wise, but I simply don't see a good reliable way to do it
 right now.

 Suggestions would be welcome.
