Baking vertex colors per-corner leads to unwanted discontinuities when there is sampling noise, for example in ambient occlusion or with a bevel shader node for normals. For this reason the code used to always average results per-vertex. However when using split normals, multiple materials or UV islands, we do want to preserve discontinuities. So now bake per corner, but make sure the sampling seed is shared for vertices.
