Tried to remix cliparts that have a realistic look by only gradients used as a base for filter testing. Since blurring filters of the source image are listed in the same list as the ones tested out, a test image better not use any filtering. Easiest would be using a raster image for that but it's no good with the cliparts -only vector- policy.
