+ * Sergio GutiƩrrez "Sergut", sergut@gmail.com
* Sproingie 3D objects modeled by: Al Mackey, al@iam.com
* (using MetaNURBS in NewTek's Lightwave 3D v5).
*
* Revision History:
+ * 01-Sep-06: Make the sproingies select a new direction after each hop
+ * (6 frames); if they fall towards the edge, they explode.
+ * (TODO: let them fall for a time before they explode or
+ * disappear) [sergut]
+ * 13-Dec-02: Changed triangle normals into vertex normals to give a smooth
+ * apperance and moved the sproingies from Display Lists to
+ * Vertex Arrays, still need to do this for the TopsSides.
+ * [gordon]
* 26-Apr-97: Added glPointSize() calls around explosions, plus other fixes.
* 28-Mar-97: Added size support.
* 22-Mar-97: Updated to use glX interface instead of xmesa one.
* xlockmore's built-in Mesa/OpenGL support instead of
* my own. Submitted for inclusion in xlockmore.
* 09-Dec-96: Written.

-/*-
- * The sproingies have six "real" frames, (s1_1 to s1_6) that show a
- * sproingie jumping off a block, headed down and to the right. But
- * the program thinks of sproingies as having twelve "virtual" frames,
- * with the latter six being copies of the first, only lowered and
- * rotated by 90 degrees (jumping to the left). So after going
- * through 12 frames, a sproingie has gone down two rows but not
- * moved horizontally.
- *
- * To have the sproingies randomly choose left/right jumps at each
- * block, the program should go back to thinking of only 6 frames,
- * and jumping down only one row when it is done. Then it can pick a
- * direction for the next row.
- *
- * (Falling off the end might not be so bad either. :) )
