    glsl-1.50/gs-max-output: new test for geometry shader amplification
    
    Test the extremes of # of GS output vertices / components per GS input
    primitive.
    
    Existing tests only cover cases of high # of components per vertex, but
    not cases of low # of components per vertex and high # of output vertices.
