Shading Tests:\n\n\
Tested with FillareaWithData primitive.\n\
(from Bottom to Top)\n\
1st row: 1. a solid red square\n\
         2. no interpolation, same as above\n\
         3. no reflection, same as above\n\
         4. enable ambient reflection, the red square looks dimmer than before\n\
         5. back face, no lighting effect, same color as in #1\n\
2nd row: 1. also enable bf ambient reflection, red square looks dimmer\n\
         2. enable color interpolation, the square is now shaded\n\
            (top: R and B, bottom R and G)\n\
         3. back face, no color interpolation\n\
         4. also enable back face color interpolation, the square is now \n\
            shaded as in #2\n\
         5. back to front face, same as #2 \n\
3rd row: all 5 squares looks the same as the shaded square with ambient\n\
         lighting in previous cases\n\
4th row: all 4 squares looks the same as the shaded square with ambient\n\
         lighting in previous cases\n\
5th row: all 3 squares looks the same as the shaded square with ambient\n\
         lighting in previous cases\n\
