Hi!
About loosing precision: there is already noise (jitter) in
real-world devices so that you can't achieve subpixel precision
anyways (unless your panel has a very low resolution). Please see my
answer to Dmitry some mails ago.
Maybe you can achieve better precision with averaging.

Anyway "input is already noisy" does not mean "so it is okay to
degrade it more". Solve it properly. That means passing calibration
data from kernel to userland.

Thanks,
									Pavel
