           Summary: Canvas: drawImage() with wrong 'image' argument type
                    should always throw TypeError
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: HTML5
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: andreas.kling at nokia.com


The in-tree test canvas/philip/tests/2d.drawImage.wrongtype.html was incorrect.
It has been fixed by Philip Taylor per http://dvcs.w3.org/hg/html/rev/adc54342f976

In the new version, we only fail the last test, passing a non-image/canvas/video element to drawImage() will raise TYPE_MISMATCH_ERR instead of TypeError.
