>+ * Both vertex shaders involved in this test have a varying float variable

>+ * qualifier while the second not. 
>+ * The test verifies that linking the 2 shaders together results in an error,

>+ * variables with the same name declared in linked vertex and fragments shaders
>+ * must match, otherwise the link command will fail.
