[Bf-committers] Getting pixel color for a vertex (the stupid way)

[Hart's Antler]

Getting a UV texture's pixel value per vertex, the stupid way.
(this should be rewritten as a C function exposed to Python)
This script does the following hack to get the pixel value:
  1. copy the object
  2. apply a displace modifier
  3. for each RGB set the ImageTexture.<color>_factor to 1.0 and others to 0.0
  4. for each RGB bake a mesh (apply the displace modifier)
  5. for each RGB find the difference of vertex locations
  6. apply the differences as vertex colors

for some reason the values are off and always tinted green.
