Observations:
    - src/gallium/state_trackers/dri/dri2.c:dri2ImageExtension advertises v15 of __DRI_IMAGE.
    - egl_dri2.c requires only v1 of __DRI_IMAGE. Maybe a higher version
      is required in practive, but the egl_dri2.c code checks only for v1.

Questions:
    1. All functions implemented in dri2.c:dri2ImageExtensions, do they
       under swrast? Honest question, because I'm no expert on
       gallium.
       
If question #1 is true, then I see no problem with your latest plan. But
maybe Emil does.

If question #1 is false, it should be straightforward to implement in
drisw.c the small subset of __DRI_IMAGE functions required for v1.
