Have tested Mac, will test iOS as well shortly.
Hmm, nope, changes the rendering of radio buttons on iOS a little bit (border around the inner circle of a selected radio button grows a lot).

Actually, that was a preexisting issue with the initialization of the CGContext! (GraphicsContext line width defaults to 0, CGContext's to 1).
Going to need to run the layout tests now...
Layout tests are happy.
