+ 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.
