/*
Version 2.x now autoMagically applies borders via CSS rules.

Opera and Chrome support rounded corners via

border-radius

Safari 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, Opera and Chrome render
their borders natively, then we only have to support IE
for rounded borders. Fortunately IE reads CSS properties
that it doesn't understand (Opera, Firefox and Safari discard them);
so for IE we find and apply -moz-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 {
  border-radius: 3ex;
  -webkit-border-radius: 3ex;
  -moz-border-radius: 3ex;
}
