[Bug?] Camera rotation using `sk::CameraTilt` and `sk::CameraPan` makes the camera also rotate on Z axis

[Davilarek]

Camera rotation using sk::CameraTilt and sk::CameraPan makes the camera also rotate on Z axis... The issue also appears in the built-in tools/camera example. Using these lines:

sk::CameraTilt(camera, nil, deltaY);
sk::CameraPan(camera, nil, deltaX);

I'm not sure if it's a bug in the engine or issue with my code somehow. Here's a video showing the issue.
