[Moo] cross-browser border-radius and the like

[stratboy]

Hi. I know that if I set opacity with setStyle/s it is setted for all
browsers. I used it a lot. Ok. What about properties like border-
radius? Does it get setted on a cross-browser manner if I set it via
mootools? And if yes, what other properties can I set cross-browser
this way? :)
