42             This is a helper class which encapsulates geometry that should be
43             painted XOR, e.g. old cursor visualisations. It decomposes to
44             it's content, so when not supporting it, the contained geometry
45             will be visualized normally.
46             Unfortunately this is still needed, but hard to support on various
47             systems. XOR painting needs read access to the target, so modern
48             graphic systems tend to not support it anymore.
