Controls how quickly the SceneView camera accelerates while it moves.
This value sets the rate the camera's speed increases when accelerationEnabled is on. The camera's movement starts at the base speed, and then increases over the duration of the movement according to this setting.
A higher value causes the camera to reach its maximum speed more quickly, which is useful for traversing long distances. A lower value provides a more gradual and subtle increase in speed, allowing for finer control over short movements.
