[Qt-qml] Rotation/RotationAnimation

[Jason H]

It looks like at a low level, we can rotate things on X/Y axis as well (flips), 
in addition to z. (flat 

spin) I am trying to figure out how to animate a flip on X or Y axis. 

There is a Rotation element that takes axis { x, y, z} but this seems for satic 
rotations.
RotationAnimation seems to leave out the axis designation and only do Z (spin).

How can I do X/Y flips in QML?

TIA
