  * This file provides a really simple implementation of the system-
  * dependent portion of the JPEG memory manager.  This implementation
  * assumes that no backing-store files are needed: all required space
  * can be obtained from 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.
