           Summary: LayoutTests for svg fail after TransformationMatrix
                    changes
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: cmarrin at apple.com


Because of the change in TransformationMatrix from doing computations in floats
to doubles, precision differences show up in LayoutTests as slightly different
numeric values. Most of these are things like 0.00 vs -0.00 and 17s vs 172.00.
Fixing DRT to get rid of these two differences will fix the problem in almost
all tests

The downside is that changing how numbers print out will require many test
results to be redone.
