I made the case for this overwrite before realizing I could just suggest the change to the original uploader. It boils down to vector > raster. Vector will look better longer and on more systems. Raster is limited and the current .jpg already appears riddled with artifact noise and degraded color.
Again, more links and info on the file's talk page.
