BTW, I've just fixed a bug in that code which caused the pnmcat stage
to fail if the smallest monitor dimension was a power of two (e.g. 
1280x1024).

Essentially, the code always added one to the number of rows and
columns (rather than rounding up), so if the image size was an exact
multiple of the tile size, you would get an extra zero-width column
and a zero-width row, which pnmcat complained about.
