a basic test of logging # of inches of a given element (using a dpi method)

// dpi.get() code is from stackoverflow:

var dpi = {
  v: 0,
  get: function (noCache) {
     if (noCache || dpi.v == 0) {
        e = document.body.appendChild(document.createElement('DIV'));
        e.style.width = '1in';
        e.style.padding = '0';
        dpi.v = e.offsetWidth;
        e.parentNode.removeChild(e);
     }
     return dpi.v;
  }
};

$(function(){
  $('fieldset')
    .filter(function(){return $(this).find('fieldset').length == 0})
    .each(function(){
      console.log("OuterHeight: ",
                Math.floor(($(this).outerHeight() / dpi.get())*10)/10,
                " inches ...->", $(this));
    });
});
