SAA_cameraDolly
Moves the camera forwards and backwards in the direction of the camera interest.
Moving the camera forwards brings the camera closer to the interest, and makes objects
look bigger, while moving the camera backwards makes objects look smaller. This function
is typically preferred to SAA_cameraZoom
because it doesn't introduce a deformation or fish-eye effect.

camera- Camera to move forward or backward. To get a handle on a camera in a scene, use
SAA_sceneGetCameras.
delta- Displacement of the camera along the line of sight. The unit of displacement is a full
length of the line of sight. For example:
- +1.0 Camera moves backwards such that the new line of sight is twice as long.
0.0 Camera stays in the same position.-0.5 Camera moves forward such that the new line of sight is twice as
small.-1.0 Camera moves to the same position as the camera interest.
