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