           Summary: Remove down-casting to BitmapImage in
                    GraphicsContext::drawImage.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Images
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: luxtella at company100.net


Add a BitmapImage draw method which takes RespectImageOrientationEnum enum as the last argument for CG. Then we can remove the conditional down-casting in GraphicsContext::drawImage.

This change is needed for parallel image decoders. Because parallel image decoders use a Bitmap image wrapper class which extends Image (not Bitmap), the down-casting above causes the loss of RespectImageOrientationEnum which must be passed to BitmapImage.
