* Tests that glGetUniformLocation() returns no location for UBO variables.

* variable associated with the default uniform block, use the command

* int GetUniformLocation(uint program, const char *name);
*
* ... The value -1 will be returned if <name> does not
* correspond to an active uniform variable name in <program>, if
* <name> is associated with a named uniform block..."
