Improved modelEyeParameters routine for handling axial length / refractive error
estimateSceneGeometry now attempts only to determine the camera extrinsic camera translation matrix; the rotationCenter of the eye is fixed by the modelEyeParameters, and is under the influence of the passed spherical refractive error of the subject and / or their measured axial eye length.
