many independent line segments

Beautiful, thanks! I didn't even have to upgrade my 0.80

BTW, Rich, I read your brainlab article in the linux journal (I
subscribe) -- it was very nice. One of the main applications I had in
mind when I wrote the line collections code was efficiently making
spike raster plots, where you have bazillions of independent line
segments. Might be useful in brainlab...

By the way, some people in our group are using p-genesis and a
collaboration with Argonne National Labs (supercomputer) to do large
scale simulations of neocortex.
