    app: check "gradient-repeat" sensitivity at Blend Options creation.
    
    When starting the tool with one of the gradient types for which the
    repeat option should be deactivated, it is not. Run the handler function
    once at GUI creation.
    Also compare the gradient type with an enum value, which makes the test
    clearer than using an int.
