           Summary: Transforms: Certain rotation angles cause borders to
                    expand
           Product: WebKit
           Version: 526+ (Nightly build)
          Platform: Macintosh
               URL: data:text/html,<div style="width: 50px; height: 50px;
                    border: 1px solid; -webkit-transform:
                    rotate(0.001deg);"></div>
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2

In the URL, the vertical borders are rendered as 3px wide rectangles, but they
should be 1px wide. It seems like antialiasing doesn't kick in at that angle,
and the coordinates get rounded to two integers 3px apart.
