Until now, the touchscreens have shown a really low mass production variance.
We're shipping precomputed calibration constants with OM-2007.2 and I didn't
hear any complaints about that. Closing as WONTFIX for now.

this is just because all the panels are from one batch at the moment. that will
definitely change in the future, and actually even half of the
currently-being-produced units might have a different batch.

Milosch's new GTA02 production process / flow will however have provision for
touchscreen calibration. The question is still how and where to store. Since
the testing software is intended to run from within a linux system, it's
probably possible to even write it into the rootfs.

The next batch of display showed no more variations. Closing this again until we
actually have a problem with calibration.
