  Revision 1.9.16.1  2008/07/29 09:26:56  nakano_yoshinobu
  Added DemoUseMEM_HEAP_OPT_THREAD_SAFE option.
  This option uses MEMCreateExpHeapEx(..., MEM_HEAP_OPT_THREAD_SAFE) in DEMOInit().

  Revision 1.9  2007/06/15 23:04:30  carlmu
  Allow XFB to be allocated from MEM2.

  Revision 1.8  2007/02/07 23:54:31  johnc
  Removed static scope from functions and variables inside DEMOInit.

  Revision 1.7  2006/08/11 09:28:45  yasumoto_yoshitaka
  surpress unused warning

  Revision 1.6  2006/03/11 06:55:23  hirose
  Integrated MEMAllocator, added switch to use heap defined in MEM library.
  Moved easy-packed tpl functions from <revolution/tpl.h>

  Revision 1.5  2006/02/04 13:05:44  hashida
  (none)

  Revision 1.4  2006/01/07 06:47:13  hirose
  Reconstruction from simpler form.

  Revision 1.3  2005/12/20 05:26:36  hirose
  (none)

  Revision 1.2  2005/08/03 02:52:20  hirose
  Substitution of obsolete charPipeline libs by new tpl library.

  Revision 1.1.1.1  2005/05/12 02:41:06  yasuh-to
