           Summary: -webkit-transform matrix does not work
           Product: WebKit
           Version: 525+ (Nightly build)
          Platform: All
        OS/Version: Mac OS X 10.4
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: erik.arvidsson at gmail.com


The matrix value for -webkit-tranform seems broken. The following value, which
means rotate 30 degrees is broken does .

matrix(0.866025px, 0.5px, -0.5px, 0.866025px, 0, 0)

This value works fine with SVG transforms and IE matrix filter so I'm pretty
sure my math is correct.

I've tried without px and with and with commas... The px is really confusing.
An affine transformation matrix should not have a unit. It seems fine to have
units for the dx and dy but not for the ohter 4 elements.

I've verified that this happens both on Windows and on Mac OS X 10.4
