- Did you mean the quality/sharpness? It's a PNG automatically converted from SVG, taken directly from https://commons.wikimedia.org/wiki/File:Merge-arrows-3.svg, it looks all right on my screen ^^
- The main reason why I've changed it is that now status templates' icons are centered in the side paddings with position:absolute, see MediaWiki talk:Common.css#Templates' CSS, but that assumes that all icons are the same width. Secondarily, I've done it for consistency.
