Um, in that case I'd rather do the storing w and h crude fix now. As I 
stated before, what I really want currently is getting the GL client to 
work, in order to have a working Gzz on my machine. The current text 
makes it unusable.

Besides, when you show a zz view in the demos, it'll look horrible if 
the text is that wrong (at least the dimension's text you can't avoid).

That doesn't answer the question. Where (code-wise) and what do we clip?

But how do we draw the connection? I know how to draw something in the 
first coordsys, but I have no idea how to draw a line between the first 
and second coordsys of a vob.

As small as normal text in a PUI, and 1 or 2pt smaller.

Ok.
