Improve the movement of an air mouse

[Tonymazzz]

Hello dear Asukiaaa, first of all congratulate you for this great library that you have provided us !!!
I have used it to create an Air mouse with mpu9250 and it works great but I know that the movement could still be improved a little more, for example, the movements are linear, it means that it is easier to draw a square than a circles, I do not know if I explain myself ...

On the other hand, in this code that I send you, I only use the gyroscope, since I don't know how to implement the accelerometer and magnetometer so that the accelerometer, gyroscope and magnetometer compensate each other and correct any drift that may occur.

And last, its there any autocalibration for the gyro and the accel when the Arduino start?
Or do i have to implement it with any code?

Any help or advice you can provide will be of great help dear Asukiaaa.

Thanks in advance :)
