A single icon's emblem can take up 25% of the total icon area in certain cases, which obscures enough of the icon that it may become hard to tell what it is. This is especially noticeable with 16x16 and 32x32 icons in Dolphin's Places Panel. See T9740#162147 for examples.
Because an icon can have up to four emblems, it is theoretically possible for a small icon with four emblems to show none of the icon itself, just emblems!
This patch adjusts the calculation so that a single emblem never takes up more then 18.75% of the total area of an icon, even at small sizes. As a result, icons are less obscured by their emblems.
