   2  * Vertex shader test.
   3  * Uses all conventional attributes and 15 generic attributes to print
   4  * their values, using printMESA() extension function, to the debugger
   5  * to compare them with the actual passed-in values.
   6  * Use different types for generic attributes to check matrix handling.
