        * configure.ac: Check for libXrender when the GTK peers are
        enabled, and set HAVE_XRENDER accordingly.
        * native/jni/gtk-peer/gnu_java_awt_peer_gtk_ComponentGraphics.c
        (Java_gnu_java_awt_peer_gtk_ComponentGraphics_hasXRender)
        [HAVE_XRENDER]: Call XRenderQueryExtension conditionally.
