Fires before an in-game or prerendered cinematic.
CINEMATIC_START : canBeCancelled
- boolean - Intuitively true when a cinematic may be interrupted by the player, but comments in the FrameXML code suggest this payload is true when the cinematic is "real".
- IsInCinematicScene() - Returns true during cinematics rendered dynamically by the game engine.
- InCinematic() - Returns true during prerendered "movie-like" cinematics.
- CanCancelScene() - Alternative to relying on canBeCancelled payload.
