* Cornerz 0.6 - Bullet Proof Corners
* 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.

CHANGELIST from  v0.4

0.5 - Now attempts to fix the odd dimension problem in IE 
0.6 - Added semicolons for packing and fixed a problem with odd border width's in IE
