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