  32  * Creates two EGL images from an ARGB8888 dmabuf, samples each one,
  33  * destroys one, then tests that the other can still be sampled.
  34  *
  35  * This gets at a common refcounting bug in drivers: GEM returns the
  36  * same handle for a given BO re-opened through dmabuf on the same
  37  * device fd, but that GEM handle is not refcounted.  The userspace
  38  * driver needs to be sure that it's doing handle refcounting itself.
