Can't render with -y about c10t

Try with 08c06d9, work has been put into doing proper projection calculations for determining image size and positioning chunks.

Just checked out the trunk and got the same error in "calc_image_partial" the topleft point is projected to an slightly negative x position. Both p.xPos and minx are negative before but canceling out to p.xPos-minx > 0

This process has been improved upon slightly, you might wish to check again.

The newest build works like a charm, thank you.
