* Jonah Fox (jonah@parkerfox.co.uk) 2008

* Usage: $('.myclass').curve(options)
* options is a hash with the following parameters. Bracketed is the default
*   radius (10)
*   borderWidth (read from BorderTopWidth or 0)
*   background ("white"). Note that this is not calculated from the HTML as it is expensive
*   borderColor (read from BorderTopColor)
*   corners ("tl br tr bl"). Specify which borders
*   fixIE ("padding") - attmepts to fix IE by incrementing the property by 1 if the outer width/height is odd.
