That is an option that is provided in JFreeChart, and so we'll modify our code to *not* use XOR in that case. But XOR saves us from having to allocate that Image for cases where the chart repaint time is somewhere in between "real fast" and "real slow". [It perhaps reflects my age that I even care about conserving memory!]

  As I mentioned, I was joking.
Yeah, I did spot that.
  However, so far I have seen very few examples where the use of Xor
  paint mode is required.
So deprecate it.  I'll miss it, but only a little.
