Error in the keyword constructor of App.Rotation (Python)

[galou_breizh]

There's a bug in the Python constructor of App.Rotation with keyword arguments: "App.Rotation(x=1, y=0, z=0, w=0)" always returns the identity rotation: "Rotation (0.0, 0.0, 0.0, 1.0)".

From the code, construction from quaternion using keywords isn't supported.

Thanks for the info!

The problem is then that this unsupported feature should raise an exception rather than ignore its input.
