           Summary: Transition from perspective(500px) to 'none' is
                    probably wrong
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org

The blendToIdentity clause in PerspectiveTransformOperation::blend() computes p as
p = p + (1. - p) * progress;

which is nonsensical. p is the perspective value (e.g. 1000), so why the 1-p?
