+Subject: [PATCH 22/50] egl/wayland: flush the drawable before blitting
+
+Flush the drawable before blitting in the "is_different_gpu" case when
+swapping buffers, and pass the flush flag to the blitImage call. The
+change brings the code into line with the way the DRI3 GLX code works.
+
+For the PowerVR driver, the drawable parameters that will be used in
+the flush have been obtained previously, including any native fence
+associated with the blit source. The blit will result in a new native
+fence for the source, and make the one in the drawable parameters
+invalid.
