[Wayland-bugs] [Bug 49002] EGL/GBM: Make it possible to share buffers from compositor to clients

--- Comment #2 from Daniel Stone <daniel at fooishbar.org> ---
EGL implementations can already send a wl_surface along to the server, but then
we need a way to indicate to gbm that a particular surface is (or isn't) a
scanout candidate. gbm can then arbitrate buffer allocations itself. This is
quite complex, but with this simple API addition, all hidden inside the
implementation:
  gbm_surface_set_scanout_candidate(struct gbm_surface *surface, bool scanout)
