Well, slow as far as I can see.

The problem is that I'm not really sure in which patch level the mouse 
support appeared.  But to be honest, I haven't put much effort into this at 
all.  It may also be possible to start gnuplot with the mouse option on from 
the command line, and check for an error code.  So few people seem to use 
gnuplot that I've been a bit lazy with this.  The ones that use it seem to 
be happy to get the mouse-enhanced version.   But I should really cook up a 
cleaner solution.
