code: public void setTextureAtlasInfo(String key, float[] offset, float[] scale) {
          setTextureOffset(key, offset);

      }
docs: Set the light map information(offset and scale) at UV space to
  map the light map texture to the mesh.
  
  @param key
  Prefix name of the uniform at light map shader:
  ([key]_texture, [key]_offset and [key]_scale.
  @param offset
  Array with x and y offset values at UV space
  to map the 2D texture to the mesh.
  @param scale
  Array with x and y scale values at UV space
  to map the 2D texture to the mesh.
