[PD] still confused about pix_snap

[Matteo Sisti Sette]

Hi,

Tnanks, that works.

One interesting thing is that here you're sending the bang to pix_snap 
immediately BEFORE it receives the gemlist, while in all the previous 
examples by yoy, IOhannes et al. (some of which crash) the bang is sent 
just AFTER the gemlist.
Is that relevant?
