- * assumes that no backing-store files are needed: all required space
- * can be obtained from ri.Malloc().
- * This is very portable in the sense that it'll compile on almost anything,
- * but you'd better have lots of main memory (or virtual memory) if you want
- * to process big images.
- * Note that the max_memory_to_use option is ignored by this implementation.
