I think so. It shows up in the gl2ps plot, but not on the on-screen
fltk plot. It looks sort of like when you convert a photograph, say of
a person's face, into an .eps file. Do you need me to draw and point
out explicitly point out what I'm referring to?

I can't think of anything other than glReadPixels. I also ask again,
is a vector image format the right format for these pictures? The 3d
surfaces produced by print also look a little weird with the fltk
backend. I didn't run Soren's script (I'm sorry, but where is the
latest version again?), but I imagine this also produces really large
image files.
