Enable/disable the use of temporal coherence during tri-mesh collision checks. Temporal coherence can be enabled/disabled per tri-mesh instance/geom class pair, currently it works for spheres and boxes. The default for spheres and boxes is 'false'. The 'enable' param should be 1 for true, 0 for false. Temporal coherence is optional because allowing it can cause subtle efficiency problems in situations where a tri-mesh may collide with many different geoms during its lifespan. If you enable temporal coherence on a tri-mesh then these problems can be eased by intermittently calling dGeomTriMeshClearTCCache for it.
