  33
  34             This is a helper class which encapsulates geometry that should be
  35             painted XOR, e.g. old cursor visualisations. It decomposes to
  36             its content, so when not supporting it, the contained geometry
  37             will be visualized normally.
  38             Unfortunately this is still needed, but hard to support on various
  39             systems. XOR painting needs read access to the target, so modern
  40             graphic systems tend to not support it anymore.
