Ah, ok, we should continue supporting both then. Maybe try to figure out
which Linux distributions still use 1.2 and once they upgrade we can
remove the old version.
Unfortunately, some drivers support GLX 1.2 only (e.g. the closed-source ati driver (fglrx) and some older open-source drivers). Supporting both is the only option for the foreseeable future...
