I was wondering if a scene took longer to parse if the scene output size
was larger... I can tell that it is during parsing that the memory usage
peaks, and during rendering it doesn't use that much memory, but I was
just wondering.  The scene I'm working on for the IRTC is taking a long
time to parse and when I assigned 50000 k of RAM to the application it
filled the bar almost completely (Yes, this is on a Mac) Fortunately I
can assign up to 110000 of RAM to the application right now, but I know
the scene will get more complicated with more objects.

I believe what you are seeing in the way of more memory usage with
larger images is the fact that more of the scene gets "seen".
This is why a small render goes so fast by comparison. There isn't as
much visible in the way of modeled objects or textures to put a ray to.
A large image is going to allow the rays to increase exponentially in
order to trace all the visible areas.
At least that's my own awkward explanation.

No, a larger image shouldn't increase the parsing-time.

in the parsing, the #while loops are the thing that takes time(and recursion),
and theese aren't affected by a larger image size. so the parsing time shouldn't
be affected by the output image.
