* Marcelo F. Vianna (Jul-31-1997)
*
* Revision History:
- * 02-Aug-97: Now behaves more like puzzle.c: first show the cube being
- * shuffled and then being solved. A mode specific option was added:
- * "+/-hideshuffling" to provide the original behavior (in which
- * only the solution is shown).
- * The color labels corners are now rounded.
- * Optimized the cubit() routine using glLists.
- * 01-Aug-97: Shuffling now avoids movements that undoes the previous movement
- * and three consecutive identical moves (which is pretty stupid).
- * improved the "cycles" option in replacement of David's hack,
- * now rp->anglestep is a GLfloat, so this option selects the
- * "exact" number of frames that a rotation (movement) takes to
- * complete.
- * 30-Jul-97: Initial release, there is no algorithm to solve the puzzle,
- * instead, it randomly shuffle the cube and then make the
- * movements in the reverse order.
- * The mode was written in 1 day (I got sick and had a license
- * at work...) There was not much to do since I could not exit
- * from home... :)
- *
+ * 05-Apr-2002: Removed all gllist uses (fix some bug with nvidia driver)
+ * 01-Mar-2001: Added FPS stuff - Eric Lassauge <lassauge@mail.dotcom.fr>
+ * 01-Nov-2000: Allocation checks
+ * 27-Apr-1999: LxMxN stuff added.
+ * 26-Sep-1998: Added some more movement (the cube does not stay in the screen
+ * center anymore. Also fixed the scale problem immediately after
+ * shuffling when the puzzle is solved.
+ * 08-Aug-1997: Now has some internals from xrubik by David Bagley
+ * This should make it easier to add features.
+ * 02-Aug-1997: Now behaves more like puzzle.c: first show the cube being
+ * shuffled and then being solved. A mode specific option was
+ * added:
+ * "+/-hideshuffling" to provide the original behavior (in which
