After creating a syncKHR object with type EGL_SYNC_NATIVE_FENCE_ANDROID, glFlush must be called before the EGL_SYNC_NATIVE_FENCE_FD_ANDROID attribute is populated with a sync fd. We currently call eglDupNativeFenceFDANDROID before issuing the flush. Bug 18052459 Taken verbatim from matthew.k.gumbel@intel.com. Change-Id: I3781d14f92862076e2bca7d27341a6dc6e7e3775
