/*
Version 2.x now autoMagically applies borders via CSS rules.
Safari, Chrome and Mozilla support rounded borders via

-webkit-border-radius, -moz-border-radius

We let these browsers render their borders natively.
Firefox for Windows renders non-antialiased
borders so they look a bit ugly. Google's Chrome will render its "ugly"
borders as well. So if we let FireFox, Safari, and Chrome render their
borders natively, then we only have to support IE and Opera
for rounded borders. Fortunately IE reads CSS properties
that it doesn't understand (Opera, Firefox and Safari discard them);
so for IE and Opera we find and apply -webkit-border-radius and friends.

So to make curvycorners work with any major browser simply add the following
CSS declarations and it should be good to go...

.round {
  -webkit-border-radius: 3ex;
  -moz-border-radius: 3ex;
}

NB at present you must (for Opera's sake) include these styles in
the page itself.
