public SurfaceData validateSurfaceData(SurfaceData srcData, SurfaceData cachedData, int w, int h)

Implements abstract sun.java2d.SurfaceDataProxy.validateSurfaceData.

Doc from sun.java2d.SurfaceDataProxy.validateSurfaceData.

Construct an alternate form of the given SurfaceData. The contents of the returned SurfaceData may be undefined since the calling code will take care of updating the contents with a subsequent call to updateSurfaceData.

If the method returns null then there was a problem with allocating the accelerated surface. The getRetryTracker() method will be called to track when to attempt another revalidation.
