/******************************************************************
 * CONFIGURATON SETTINGS - you can change these, and then rebuild
 *   ODE to modify the behavior of the library.
 *
 *   dSINGLE/dDOUBLE   - force ODE to use single-precision (float)
 *                       or double-precision (double) for numbers.
 *                       Only one should be defined.
 *
 *   dTRIMESH_ENABLED  - enable/disable trimesh support
 *   dTRIMESH_OPCODE   - use the OPCODE trimesh engine
 *   dTRIMESH_GIMPACT  - use the GIMPACT trimesh engine
 *                       Only one trimesh engine should be enabled.
 *
 *   dUSE_MALLOC_FOR_ALLOCA (experimental)-
 *                       Use malloc() instead of alloca(). Slower,
 *                       but allows for larger systems and more
 *                       graceful out-of-memory handling.
 *
 *   dTRIMESH_OPCODE_USE_NEW_TRIMESH_TRIMESH_COLLIDER (experimental)-
 *                       Use an alternative trimesh-trimesh collider
 *                       which should yield better results.
