It's not a problem with VolatileImage. I wanted just meant, that I could have
created a BufferedImage and rendered in that BufferedImage. Alas, it implies
that I have to manage this BufferedImage depending on the JPanel/JScrollpane
and to disable the double-buffering in the JPanel to get maximum performance.
(it's no so complex, but if I can avoid some work...)

It's why I would prefer not to use a such flag ;-)
