The abstraction you are looking for can be found in:
Take a look at /Developer/Examples/Quartz Composer/Applications/Poster
From the Read Me:
Poster Shows how to tile the rendering of a QCRenderer's composition
by modifying appropriately the OpenGL projection matrix.

Right now I'm putting together a project that lets me randomly
generate static compositions on a mouseclick, and while screen-
resolution size is fine for projecting or electronic display I'd
like to output a series of compositions to at least A3/poster size
so I can display them. My first thought was to simply export a
quicktime movie of that size (about 3508 x 4961 px, for a 300dpi
composition), but then I've butted up against the 2048 x 2048 limit
so I guess I'm sort of stuck, there. Printing just lets me get a pdf
of the editor page, and dividing the composition into a bunch of
different squares that I can composite together just sounds like a
really messy solution (and also impossible, given the randomness of
the actual composition). Is there anything I can do to work around
this? I've started in QC because it's what I'm most comfortable
with, but it feels like it's not the best purpose for QC, and I
might move to Flash if I have to. Thanks.
