Library to handle Tooltip Extensions.
There are addons that would need to add extra frames that extend game tooltips.
For example, consider the item tooltips:
An inventory addon could want to add data of number of similar items you have in your alters inventory, bank, guild bank...
An auction house addon could want to add data of market price, sales volume...
A gear management addon could want to add info of gear sets to which the item belongs.
A crafting addon could want to add info of recipes that require the item.
A questing addon could want to add info of quests where the item is needed.
With so many addons requiring to extend the tooltip, each one implemented by a different author in a different way, it becomes inevitable some of them clash, causing rendering issues and increasing overall CPU usage.
What this library aims to is to provide an unified and easy way to extend tooltips, while preventing rendering issues and reducing the number of API calls by sharing common data.
