[PD] gemwin size and printouts

[marius schebella]

hi,
today I was trying to create some printable screenshots, tried to get 
the largest size out of gem. I ran into some limitations with gemwin. 
the biggest possible size I could render was ~3560*3560 with FSAA 2. I 
wonder if this is a GPU memory limitation (256Mb) or a limitation of the 
window manager. Is there a way to render with even higher resolution, 
could be directly to disk.
I don't have much experience with big printings. has someone tried to 
use hi-res gem stuff for print?
thanks.
