Resizable: in event resize when using grid ui.size does not honor the grid

[mmoossen]

Given the following code, the event will be fired continuously as if ignoring the grid option.

      $div.resizable({
        grid: [10, 10],
        resize: function(/**Event*/event, /**UIHelper*/ui) {
                  $width.val(ui.size.width + 'px');
                  $height.val(ui.size.height + 'px');
                }
      });

I did fix it with following code:

        resize: function(/**Event*/event, /**UIHelper*/ui) {
                  // HACK: we can not use ui.size because of bug #4500
                  var /**int*/width = $div.css('width');
                  var /**int*/height = $div.css('height');
                  if ((width == $width.val()) && (height == $height.val())) {
                    // prevent unneeded calls
                    return;
                  }
                  $width.val(width);
                  $height.val(height);
                }

And of course, /int*/ should be /String*/ ;)
