When using the Normal output of the Texture Coordinate node on Point and Spot lamps, the coordinates now depend on the rotation of the lamp. On Area lamps, the Parametric output of the Geometry node now returns UV coordinates on the area lamp. Credit for the Area lamp part goes to Stefan Werner (from D1995).
