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
