26 * Sproingie 3D objects modeled by: Al Mackey, al@iam.com
27 * (using MetaNURBS in NewTek's Lightwave 3D v5).
30 * 01-Sep-06: Make the sproingies select a new direction after each hop
31 * (6 frames); if they fall towards the edge, they explode.
32 * (TODO: let them fall for a time before they explode or
34 * 13-Dec-02: Changed triangle normals into vertex normals to give a smooth
35 * apperance and moved the sproingies from Display Lists to
36 * Vertex Arrays, still need to do this for the TopsSides.
38 * 26-Apr-97: Added glPointSize() calls around explosions, plus other fixes.
39 * 28-Mar-97: Added size support.
40 * 22-Mar-97: Updated to use glX interface instead of xmesa one.
41 * Also, support for multiscreens added.
42 * 20-Mar-97: Updated for xlockmore v4.02alpha7 and higher, using
43 * xlockmore's built-in Mesa/OpenGL support instead of
44 * my own. Submitted for inclusion in xlockmore.
