+Subject: [PATCH] [GTK] Build failure with ACCELERATED_2D_CANVAS when cairo-gl has
+ built with OpenGLESv2 support only.
+
+When cairo-gl is built with GLX and ACCELERATED_2D_CANVAS if cairo-gl was only
+built with OpenGLESv2, cairo-glx is not enabled causing
+Source/WebCore/platform/graphics/glx/GLContextGLX.cpp to reference an undeclared
+function and cause a compliation error. Adding an extra check resolves this
+build failure.
+
+Upstream-Status: Backport [webkit-2.10.0]
