+        [EFL][WebGL] Add proper checks to enable GraphicsSurface usage on EGL without XCompositeWindow.
+        https://bugs.webkit.org/show_bug.cgi?id=108034
+
+        Reviewed by Laszlo Gombos.
+
+        Covered by existing WebGL tests.
+
+        Currently, we set GRAPHICS_SURFACE to true if support for XCompositeWindow
+        is identified during compile time. This is ok, when using GLX. We might not
+        have support for XCompositeWindow when using EGL and GLES2.0. This patch
+        makes changes so that GRAPHICS_SURFACE is always enabled with EGL and adds
+        GLX guard to the parts of code dependent on XCompositeWindow support.
