The error is not the fact that it's negative.  The error is that after 
stuffing it into an (unsigned int) it looks like a huge positive number
instead.

That would be a big change, though.  Right now we leave a lot of
the clipping to the individual terminal drivers.

The problem I've run into is that the PDF library doesn't clip in
these cases, it just causes the program to exit.  
*Any* solution that leaves you inside gnuplot is better than what
it is doing now.
