the gen X11 backend is useful as a fail-safe fallback when the other
ones don't work; i've got bad experiences running some of the bibisect
repos on Fedora 27 where gen is the only one that doesn't crash on
startup, and i guess one of the reasons for that is that ~nobody does
changes in gen or the system's X11 libs nowadays.

so i'm mostly interested in preserving gen as-is and not adding fancy
new stuff with unknown compatibility issues to it...
