Notes

• Patch 1.11 introduced RaidIcons for easier targetting. This function sets an icon on top of a targets head.
• Setting the same icon twice to the same target will drop the icon.
• SetRaidTarget is the native API function used (and does not exhibit the toggling behavior); see also GetRaidTargetIndex.
