      36             :             painted XOR, e.g. old cursor visualisations. It decomposes to
      37             :             it's content, so when not supporting it, the contained geometry
      38             :             will be visualized normally.
      39             :             Unfortunately this is still needed, but hard to support on various
      40             :             systems. XOR painting needs read access to the target, so modern
      41             :             graphic systems tend to not support it anymore.
