Actually, more likely with the OpenGL/GLX implementation in the X
server, i.e. in paractice, most likely in the Mesa code shared between
the X server and the DRI 3D drivers.

Apparently, when it says 'hardware-neutral parts of DRI', it really
means 'X server parts of the DRI' (which aren't necessarily
hardware-neutral)?

Only the latter is really required for this, the (non-)presence of the
former doesn't matter if the DRI is disabled in the X server.
