I want to finally resume work on #Xmoji. Starting with a bit of house-keeping, I factored out a function probing for a weird #XRender (presumably only with #glamor) bug, so it doesn't distract from the normal X client startup, and took the opportunity to also document it:

https://github.com/Zirias/xmoji/blob/7d617cd74813590c08182bf963c622d219842b17/src/bin/xmoji/x11adapter.c#L623

If anything is really wrong with #X11 or #XOrg, it's bugs like this 😔 ...
