           Summary: [Qt] Consider prefering QImage* over QPixmap* as
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: NEW
          Keywords: Qt
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: zecke at selfish.org

We need to find out if for the majority of cases of painting images we are
going through the raster fallback or through the accelerated path of the
PaintEngine. The problem in Bitmap::drawImage is that we will probably scale
the image which means that the raster engine will need to convert the QPixmap
back to a QImage which is requiring a roundtrip for every image we paint.

The performance test content should be used to determine how often we are going
through the draw_helper for image painting.
