[Bf-python] Contrib Addon Review: uv_bake_texture_to_vcols

[Campbell Barton]

This addon is handy, copying pixel color to vertex color is useful.

Having this addon do color mixing is handy but seems a bit unrelated.
We could have it just add a new vertex color layer, then add a way to
mix 2 layers together built into blender which could be useful in
other cases too.

IMHO Not a reason to remove the feature, just think it could be done
differently long term.

While reading the script I noticed...
- It assumes the first faces image is the same for every other face
(not always the case)
- Uses while loop to get the constrainted UV's rather then (value % 1.0)

So needs a code review but can go in.
