Blurred Paint Attr

The render for rust and water drips had harsh edges on the displacement due to the point color attributes. To fix that, I plugged the paint sop into an attribTransfer sop (both inputs) and bumped the radius up to 1.64 and the samples to 15. This gave a nice falloff to the rust and is an added feature for the user in that they can now control how soft they want the falloff to be on the rust. This is the odforce post I found that described it.
