[PRQ#48915] Merge Request for agg

MarsSeed [1] filed a request to merge agg [2] into agg-2.6-git [3]: 'agg' is abandoned package on AUR, for Fedora's legacy agg v2.5 distribution; dropped by them in 2016. AUR/agg's source is missing (404 not found). agg-2.6-git is a maintained continuation fork, which doesn't have release tags. Potential users of AUR/agg have been notified in 2022 by @cmsigler about the status of that package and the continuation fork.
