I noticed Sproat calls it roll: "How to roll the camera", but he also says:
"I'm really talking about tilting the camera to one side."
And to me (being a non-English-native) roll is more ambiguous than tilt.
Anyone else ?

It doesn't seem to work with e.g. -cg30,90
I think you need to roll the actual sky vector, and not the initial -y.

Yaw ? You said you would call it roll ?
