[cups.bugs] is this a bug in image.c?

First, you can set RIPCache to a small number to simulate a low memory situation.

Second, the pos member is initialized to -1 when the tile array is created, and then assigned a position in the file in flush_tile() as needed.

Finally, I recently fixed a bug in this code where cachefile was not initialized to -1, so all cache data would be written to stdin; changes are in trunk...
