Hi Andy,

Sure, I did try to print invisible figures and it works almost all the time.
I don't always obtain the same results as you (e.g. in [1] copyobj demo 1,
the legend is not rendered for me)
but I suppose it has to do with the Octave executable __gl_print__ is
compiled against. I used the default 0ctave executable (3.8.1 on my system).
Should I change the PATH environment variable or is there a better way to
point to another Octave executable?  
What are the current known limitations (e.g. I see that colorbars are not
always right)?
