+ * Negative test for inconsistent centroid qualifier usage between vertex
+ * shaders.
+ *
+ * Both vertex shaders involved in this test have a varying float variable
+ * with the same name. But the first shader declares it with the centroid
+ * qualifier while the second not.
+ * The test verifies that linking the 2 shaders together results in an error,
+ * according to GLSL 1.20 section 4.3.6:
+ * The type and presence of the centroid and invariant qualifiers of varying
+ * variables with the same name declared in linked vertex and fragments shaders
+ * must match, otherwise the link command will fail.
