Fix: Camera movement flagging

[fallenoak]

Billboarding needs to update whenever the camera rotation OR position changes, and not just when camera rotation changes.

Ah good point! :+1:

What about movement/rotation of the actual billboarded doodad/unit? Not sure if that occurs anywhere in the game.

Hmm, good question. So far, I've only come across billboarding on M2s that are fixed in position (map doodads). Maybe it's best to tackle billboarding for moving M2s when we come across one.

Let's do that :+1:

Woohoo!
