// @TODO:
//  - Trigger blue camera on minimap.
//  - Ability to disable more inputs in freecam.
//   - Update default binds.
//   - Bind to change preset.
//   - Bind to reverse freecam input (left AND right stick no effect on camera).
//  - Display equiped armor in the debug UI.
//  - Manully set freecam viewport index.
//  - Override in-game viewmode.
//  - +right and +forward to move character.
//  - Keyframes?
//  - Special case freecam for cutscenes and canteen animations.

// Test cases:
//  Offset Perspective:
//   - For all cases roll should an extra consideration.
//   Constant FOV:
//    - In quest book/board GUI (uses player camera).
//   previousCameraAnimState = 5 (Don't apply offset):
//    - Zoom into quest board or The Handler's book.
//    - Open map animation.
//    - Entering/Leaving tent.
//   previousCameraAnimState = 4 (We choose to apply offset):
//    - Quest depart/return.
//    - Traveling on the lift in Astera.
//   previousCameraAnimState = 2 (Apply offset):
//    - Point camera towards quest board.
//   Player camera is the target of a transition:
//    - Leaving dialoge with NPC (The Handler, The Smithy, pub lasses, etc).
//    - Getting up from hot spring.
//    - Getting up from canteen.
//    - Getting up from cart.
//    - Seasonal gathering hub cutscene.
//   Directly moves player camera:
//    - Look at monster.
//    - Scoutflies point in a direction.
//    - Mount monster.
//  Free Camera:
//   - Toggle rapidly and there should be no visual jump.
//   - Story cutscenes.
//   - Canteen cutscene/animation.
//   - Inside tent.
//    - Equipment select inside tent.
