// 1. Check if the original icon is already circle shaped. If it is, then
//    return the original input icon.
// 2. Find the scale required to resize and fit the original icon inside of
//    a new circle background.
// 3. Scale down the icon and draw it over a background circle. Return the newly
//    generated icon as the standard icon.
