You can always calibratate and cacluate the raw x and y edges a little
better, but alot depends on how good your touchscreen is, and how good the
jitter control is in the touchscreen driver. I have an fairly good SA1100
touchscreen running right now, and I still get a lot of jitter and bad
points, especially as I move to the edge of the screen. Thats just part of
the game, I'm afraid.
