The application below shows, that mouse X coordinates, returned by inputManager.getCursorPosition() are probably pixels.
Simultaneously, the accumulated value from analogListener is not measured in pixels, and varies from 0 to 0.6.
What are units for it? And is it possible to obtain mouse coordinates in the same units (without shown manual accumulation)?

When experimenting with rotating a sphere, I noticed, that if speed is set to 10, then rotation was occurring visually exactly as if I was dragging the surface by the mouse. Since initial setup contains camera at a distance of 10 from origin, then the units are probably radians relative to origin, but I see no confirmation for this yet.
