I used the VisualStudion 5 (reference) documentation while implementing this
and I remember that it was not very clear how things work. When it
worked for me (WireFrame) I thought I got it. Seems like it was not the
case :-/

Fine and thank you for your effort. I will integrate the changes into
my local version. I also hope to include the Point-buffer stuff we
discussed on Thursday. If I do I will publish a new version of the X11
version of VO. This will include other changes to certain files
I did while porting. As a result some file currently in the windows
changes can be removed...
