Out of memory

[neokabuto]

Larger maps and/or larger scales (a medium at 75% will do it) will cause a crash from memory running out.

It might be a bit more work than necessary, but maybe have the program render the files separately and stitch them together, almost cloning the way that DF renders it's maps, which I believe is in chunks for maps larger than medium.

Fixed in the next version.
