           Summary: [Qt] shadowBlur should not be affected by scaling
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Canvas
        AssignedTo: webkit-unassigned at lists.webkit.org

>From the spec at http://dev.w3.org/html5/2dcontext/#dom-context-2d-shadowblur :
"The shadowBlur attribute specifies the level of the blurring effect. (The units do not map to coordinate space units, and are not affected by the current transformation matrix.)"

Currently, blurring is applied in the untransformed layerImage. When layerImage is transformed and displayed on screen, the blur radius will also be affected by the scaling factor. The solution is dividing the blur radius by the balanced (X and Y) scaling factor.
