I was thinking of e.g. creating thin wrappers for the DRI_IMAGE* DRI
extensions (which are used for the EGL image API as well) in
xserver/glx/ for use by glamor. But I haven't looked into whether this
would be feasible at all or how much effort it would take in any detail.

I don't really understand how that would work. :)
