fixed:
*transmit value removed from ambient light to avoid parse warning
How do we generate a transparent background now ?
*name 'using_uberpov' was not defined in shading.py
added:
*moved exportPattern(texture) from render.py to shading.py
*moved texture influences from render.py to a function in shading.py
