McDonald 48

If he touched it, it's gold. No one even does 48px icons anymore...

Nevertheless fixed a few details and added a few details

• Added a lot of tints
• Made corner radii consistent between arrows and corner indicators (arrows were sharper–tradeoffs involved but consistency looks better to me)
• Rounder corner radius, plus more breathing room in the padding
• Added lighting highlights, gloss, and shading—plus a decorative gradient on the arrow stroke
• Made stroke width consistent on the outer border
