In this example of two buttons in a single view the bezel style has a huge effet on  button height: without the comment the buttons take up the full height of the screen
but then with the line uncommented and setting a rounded style even for one button makes both have regular size
    y.set_bezel_style(BezelStyle::RegularSquare);
    n.set_bezel_style(BezelStyle::RegularSquare); // BUGS: RegularSquare, ShadowlessSquare,SmallSquare,TexturedSquare break become vertical 100% of the height
    // n.set_bezel_style(BezelStyle::Rounded); // OK even if button Y is untouched
