[classlib][swing] Performance improvement for javax.swing.RepaintManager

                 Key: HARMONY-4777
                 URL: https://issues.apache.org/jira/browse/HARMONY-4777
             Project: Harmony
          Issue Type: Improvement
          Components: Classlib
            Reporter: Igor V. Stolyarov

I would like to suggest performance improvement for javax.swing.RepaintManager. I suggest
using as a offscreen buffer VolatileImage instead BufferedImage.  It should gives significant
boost on any types of Drawing operations. According to Spec VolatileImage can lost content,
but Harmony implementation of VolatileImage based on GDI Bitmap which always keep content.
