    app: "Reset to default values" does not properly reset aspect ratio.
    
    Generated brushes can have specific aspect ratio, hence resetting to
    fixed property defaults may be wrong. Therefore GimpPaintOptions needs
    to redefine the reset() method from GimpConfigInterface.
    Note: the specific "Reset aspect ratio to brush's native aspect ratio"
    button was alright. But the broader "Reset to default values" was not.
