/* 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].
*
* This test differs from aggregate-initializer-sized-array.shader_test in that
* it specifies one dynamic variable, to further test the compiler. Otherwise,
* the initializer is constant folded away. The arrays should still be identical.
