lookAt() results in localRotationX/Y/Z = 0

[GoogleCodeExporter]

What steps will reproduce the problem?
1. create a Camera3D (do not add to the scene)
2. orbit around a target: camera.orbit(camPitch, camYaw, true, camTarget);
3. trace camera.rotationY and camera.localRotationY while orbiting

What is the expected output? What do you see instead?
Since the refactoring to the left-handed system, it is expected that
rotationY doesn't produce the correct value, but localRotationY should!

What version of the product are you using? On what operating system?
rev 706, Vista Ultimate 32bit

Please provide any additional information below.
I've traced the problem back to the lookAt() method. Here the
localRotationX/Y/Z are reset to 0 if (_zAxis.modulo > 0.1): this always
results to "true".

localRotationX/Y/Z are *incremental* rotations.
The lookAt() method influences the *absolute* rotation of an object.
Hence: after a lookAt() localRotationX/Y/Z *must* be reset to 0.

Above bugreport should have been about obtaining the correct rotation of a 
camera.

When orbiting a camera and tracing its rotation & localRotation I cannot get the
correct rotation. The rotation is capped between -90 and 90 on both sides of 
the 360
degrees.

Could you elaborate on how one gets the correct rotation of a camera/do3d?
