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