Yea that's right. So my hope was to take it more or less from the patch, I've
linked to at top.

My last try to use meshes in CSGs is long time ago (dono what version) anyway
PovRay was not able to do the CSG. I remember once there was a way in MegaPov,
giving an option of saying where in insight and outside. I've never get this to
Is it working by now? Would be very cool! Maybe I should give it a try again.

I found a printers-types so far, able to use Pictures. Its using powder as
layers and a kind of a head, coming from a printer (ink-jet). It just "prints"
out the pictures onto the powder and do the next layer.
It cam be a very nice result, but can take 11 hours for one centimetre :P
I think that's, what the option of exporting a .png -sequence out of slic3r is
