Details

Large border radii end up generating large clip masks. When we run into problematic cases (for example 1000px radius), we could render the rounded rectangle as a grid with more than 3 cells in each dimension so as to be able to remove fully opaque and fully transparent parts of the corners.
Glenn suggested this optimization during the last allhands but I don't think we filed a bug for it.
