Today during the conf call, we spoke about the interoperability of the  
outline property.

I've put together a very simple file illustrating an interop problem with  
regards to transformed elements.

Gecko and webkit transform the outline, while presto draws an straight  
outline around the transformed element. (I don't know what IE does, as I  
run linux).

I think the problem with firefox's and webkit's approach is when you start  
to have 3d transforms. I don't think transforming the outline in 3d is a  
good idea. It works ok when people use it as a second border, but not when  
it is supposed to related to focusing.
