Issues with unsupported toolkit functionality

Right. This seems to be fairly easy to implement.

Yeah, I think that should be good enough especially for testing. For
real platform ports, this would need to be integrated with the platform
clipboard, but this is not part of core Cacio anyway.

Oh yeah, we don't provide an implementation of that one yet, and it
simply falls through to the JDK SunToolkit implementation, which of
course does not work. Should be fairly easy to implement though.

Thanks a lot! I will fix the above mentioned issues as soon as I find
some time and then probably push out a release.

Cheers,
