primitivus: better popup sizing: - showPopUp now takes absolute height and width, this makes more sense than the relative ones used before - if height or width is not set, a default is used which depend of the type of the widget (it's smaller if the widget is a note) - size is set to a low value for widget alerts - size is bigger else fix 324
