Additional Information

DirectDraw rendering

DirectDraw (DD) is the new way of rendering the Swing application to HTML canvas element. Compared to the old method, where the rendering is based on png images, this new way directly interprets the draw instructions on canvas. So the difference is similar as if you compare raster and vector graphics. DD should bring performance improvements in rendering speed and data transfer bandwidth size because it reduces the use of expensive png encoding.
