[Fluxus] texture to pixels

[gabor papp]

i'm trying to upload a texture image to a pixels primitive, but had no 
luck so far. although pixels->texture exists, texture->pixels does not, 
and i don't know if it's possible to read the pixels of a texture. is 
this possible?

while playing with this, i tried to save a pixels primitive, which 
resulted in a segfault.

(with-primitive (build-pixels 10 10)
     (save-primitive "pix.obj"))

best,
gabor
