+ * This test verifies that the vertex shader related tokens of
+ * ARB_pipeline_statistics_query() work as expected. OpenGL 4.4 Specification,
+ * Core Profile.
+ *
+ * When BeginQuery is called with a target of GEOMETRY_SHADER_INVOCATIONS,
+ * the geometry shader invocations count maintained by the GL is set to zero.
+ * When a geometry shader invocations query is active, the counter is
+ * incremented every time the geometry shader is invoked (see section 11.3).
+ * In case of instanced geometry shaders (see section 11.3.4.2) the geometry
+ * shader invocations count is incremented for each separate instanced
+ * invocation.
+ *
+ * When BeginQuery is called with a target of GEOMETRY_SHADER_PRIMITIVES_-
+ * EMITTED_ARB, the geometry shader output primitives count maintained by the
+ * GL is set to zero. When a geometry shader primitives emitted query is
+ * active, the counter is incremented every time the geometry shader emits
+ * a primitive to a vertex stream that is further processed by the GL (see
+ * section 11.3.2). Restarting primitive topology using the shading language
+ * built-in functions EndPrimitive or EndStreamPrimitive does not increment
+ * the geometry shader output primitives count.
+ *
+ * (The chicken clause)
+ * The result of geometry shader queries may be implementation dependent due
+ * to reasons described in section 11.1.3.
