+Subject: [PATCH 5/9] Fix build when EGL_MESA_screen_surface extension isn't
+ present
+
+The EGL demos won't build against EGL implementations that don't support
+the EGL_MESA_screen_surface extension. Fix this, in most cases, by
+wrapping relevant bits of code in #ifdef EGL_MESA_screen_surface.
+
+Signed-off-by: Frank Binns <frank.binns@imgtec.com>
+
+Applied and fixed up in Yocto by...
+
+Integrated-by: Tom Zanussi <tom.zanussi@linux.intel.com>
