+/* The ARB_shading_language_420pack suggests:
+ *
+ *    Verify that the following two arrays are identical:
+ *
+ *        vec4 a[12] = vec4 [] (vec4(1.2), vec4(0.0), vec4(0.0), vec4(0.0),
+ *                              vec4(0.0), vec4(0.0), vec4(0.0), vec4(2.4),
+ *                              vec4(0.0), vec4(0.0), vec4(0.0), vec4(0.0));
+ *        vec4 b[12] =        { vec4(1.2), vec4(0.0), vec4(0.0), vec4(0.0),
+ *                              vec4(0.0), vec4(0.0), vec4(0.0), vec4(2.4) }; [sic]
+ *
+ * Of course, it means to include a final row of four vec4(0.0) in the initializer
+ * of b[12].
