* iio: switch to maximum sampling frequency, apply mount matrix
* mag: Apply mount matrix for magnetometer, too
* iio: allow separate path for gyro sensor
* gyro: fork from compass, get drawing back to work
* iio: add todo.
* gyro: gyro seems to work way better on pinephone
* iio: move scale conversion where it belongs
* gyro: rely of iio driver providing right scale of values
* iio: Turn down debugging, but I still get framerate drops
* gyro: add reset and calibration support, introduce vectors, display help image
