[OpenJDK 2D-Dev] How to use D3DRTTSurfaceToSurfaceBlit

Hello Mikhail,

  -Dsun.java2d.d3d=false can be used to disable d3d pipeline.
   You can use -Dsun.java2d.trace=log to see what particular
  operations are performed by the pipeline.

  The blit that you refer to likely can be used when you render
  a volatile image to screen. However, any swing app may run
  into this blit due to buffering. For example, I can see it in a trace
  of the Notepad demo.

   Hope it helps.
