In preProcess, the GaiaTranslator must be used if the coordinate is not 4326

[sdson]

When the coordinate is 4326, the transform matrix of the rootNode has longitudeDeg, latitudeDeg an altitude in the transformMat[11], transformMat[12], transformMat[13], so when calculate the boundingBox, this values is added in the box.

When the coordinate is NOT 4326, the transform matrix of the rootNode has values in meters in the transformMat[11],
transformMat[12], transformMat[13] there are the position in meters, so there are no problem when calculating the bounding box.
