I have an application that is spending 25% of its time in
  sun.java2d.pipe.DrawImage.blitSurfaceData
19% of which comes from paintImmediately calls from the RepaintManager (call
trace at end of message).

Are the offscreen buffer images for my windows or subcomponent JPanels not
getting accelerated?  Or is this normal behavior?
