Main point is they are not *that* huge? The [largest digital photo in
1999] was bigger.

Essentially, it's not unreasonable to have a working set larger than
2GiB. With some sample inputs my final output then is ~10MiB as png.
It's fine for the allocator to say you can't have N bytes because the
machine can't provide it, rather than because it doesn't fit in int32?

In practice I am also tiling above the level of pdftoppm, but in
development wanted the flexibility of picking the tiling parameters to
find the best combination. It's likely to be smaller, say 8192x8192,
in deployment.
