Interface looks sane.  I'd like to see a more descriptive name than just
"2" though.  Maybe "dpy_gl_scanout_dmabuf"?  And while being at it
rename the other one to "dpy_gl_scanout_texture"?

Also: please put the spice update into a separate patch.

Adding gtk (or sdl2, or both) support would be nice, to see whenever the
interface works if qemu needs to import the dma-buf for display.

cheers,
  Gerd
