These features sound great. We've been hearing for a while about things 
in "gnuplot 4.1", but there's still no actual release. Are there any 
gnuplot developers who read this list? Can a release be expected any 
time soon? Some of these features are really needed to improve octave's 
graphics, but most users aren't willing to download CVS to get them, and 
I don't think it makes sense to start rewriting octave's plot interface 
to use them until a release exists.
