[PD] GEM Multiple Machines render one a cropped scene

[Max Neupert]

hi patrick,

off cause i know lighttwist of the SAT, as you know i was in residence 
there... my friend j-p. tardif is developping it for s. roy.
but isn't it a lot simpler what i want to do, compared to projecting 
with multiple projectors on a dome?

what i want is just a simple dual-screen... i bet there is a way with 
GEM only.
