*
* The original code for this mode was written by Mark J. Kilgard
* as a demo for openGL programming.
*
* Porting it to xlock was possible by comparing the original Mesa's morph3d
* demo with it's ported version to xlock, so thanks for Marcelo F. Vianna
* (look at morph3d.c) for his indirect help.
*
* Thanks goes also to Brian Paul for making it possible and inexpensive
* to use OpenGL at home.

*
* Eric Lassauge (May-13-1998)
*
* REVISION HISTORY:
*
* E.Lassauge - 03-Feb-2004: Integrated diffs from xscreensaver-4.15 : corrected gradient stuff
*
* E.Lassauge - 09-Apr-2003: Corrected parse_image_data to finally have the texture !!!
*
* E.Lassauge - 21-Jan-2002: Integrated diffs from xscreensaver-4.00
*
* E.Lassauge - 28-Nov-2001: Integrated diffs from xscreensaver-3.34
*
* Jamie Zawinski, 2-Apr-01: - The fishies were inside out! The back faces
* were being drawn, not the front faces.
* - Added a texture to simulate light from the
* surface, like in the SGI version.
*
* E.Lassauge - 01/03/01 : Added FPS stuff
*
* David A. Bagley - 98/06/17 : Add whalespeed option. Global options to
* initialize local variables are now:
* XLock.atlantis.cycles: 100 ! SharkSpeed
* XLock.atlantis.batchcount: 4 ! SharkNum
* XLock.atlantis.whalespeed: 250 ! WhaleSpeed
* XLock.atlantis.size: 6000 ! SharkSize
* Add random direction for whales/dolphins
*
* E.Lassauge - 98/06/16: Use the following global options to initialize
* local variables :
* XLock.atlantis.delay: 100 ! SharkSpeed
* XLock.atlantis.batchcount: 4 ! SharkNum
* XLock.atlantis.cycles: 250 ! WhaleSpeed
* XLock.atlantis.size: 6000 ! SharkSize
* Add support for -/+ wireframe (t'was so easy to do!)
*
* TODO :
* - better handling of sizes and speeds
* - test standalone and module modes
* - purify it (!)
