Re: [CSS3 Backgrounds and Borders Module] : 1 pixel corner color

Maybe we could say that the color of the lower right pixel is defined by two
rules. (border-right and border-bottom). If they "conflict" (meaning the UA
has to choose between the two / half-and-haf rendering is not possible), the
latter rule must be followed?

In this case, the lower right pixel would be red (following border-bottom)
and the lower left pixel would be blue (following border-left).
