@OfficerAction: Yeah, I saw that a rotation could be fed, I just hadn't seen a frontend bit to confirm what you were feeding it, exactly

.
(I'm *hoping* Qt can actually deal with the various protocol quirks sanely on its own (at least for basic touch events, multi touch gestures might be a tougher ask), but I wouldn't necessarily bet my life on it ^^. IIRC, the Aura One is using roughly Multi Touch B w/o ABS_MT_SLOT and w/ possibly broken timestamps (since boot instead of epoch, AFAIR)).
Which leads to my next question: do you deal with rotation in your app, and if so, how? (hardware fb rotations, or a rotated sw viewport?).
