+    This class setup a single threaded apartment (sta) thread to deal with
+    the ole clipboard, which runs only in an sta thread.
+    The consequence is that callback from the ole clipboard are in the
+    context of this sta thread. In the soffice applications this may lead
+    to problems because they all use the one and only mutex called
+    SolarMutex.
+    In order to transfer clipboard requests to our sta thread we use a
+    hidden window and forward these requests via window messages.

+    - if the transferable contains text data always text and unicodetext
+      will be offered or vice versa
+    - text data will be automatically converted between text and unicode text
+    - although the transferable may support text in different charsets
