      Description

      We should consider adding general scale and transform loops, similar to
      what OGLGeneralBlit provides today. This was originally described in
      6203966, and became more apparent while investigating 6248559 and
      6248561. The benefit (potentially) would be improved performance when
      scaling/transforming source images for which we do not have direct loops
      (e.g. IntArgb or ByteIndexed). Without these general scale/transform
      loops, we end up falling back on the general TransformHelper-based transform
      loops in DrawImage.renderImageXform(), which can be less than efficient
      than using OGL to do the transform.
