[cp-patches] FYI: CSS border support

[Roman Kennke]

The attached patch adds support for CSS borders. This implementation is
actually much better than Sun's because it not only recognizes the
border-width attribute (which Sun doesn't, except for 0 and 1 borders),
it also recognizes the border-top-width, etc for installing different
borders on different edges. I also added support for border-XYZ-color
and border-XYZ-style (both of which Sun doesn't support yet). I am
missing most border styles though (Sun too btw).

This is an example of how it might look:
