[Bf-committers] Patch 7891: RGB Curves node black/white point

["Björn C. Schaefer"]

Hello list,

this is my very first tiny contribution to blender, so I hope I don't 
break any protocols by posting here...

While doing some photo enhancements I noticed that it's possible to set 
the black/white point in the curves tool in the image window. My patch 
adds that functionality to the RGB Curves compositing node:

Looking forward to your feedback,
all the best,
Björn
