Touch input smoothing

Somebody in the thread at some point said:
| Is there any information out there regarding how the touch screen, and
| ultimately X processes, touch input? In particular, does it register
| one single point or perform an average over some area? If it does not
| do the latter, I would like to try experimenting with implementing
| that to get more accurate touches. This would, of course, assume that
| one could get all that data out of X or the hardware.

I have patches to improve this on andy branch, but I am currently
drowning with more critical problems.  In a week or two the touchscreen
performance will radically improve without changing userspace.
