 [Many Cubes](../examples/stress_tests/many_cubes.rs) | Simple benchmark to test per-entity draw overhead. Run with the `sphere` argument to test frustum culling
 [Many Foxes](../examples/stress_tests/many_foxes.rs) | Loads an animated fox model and spawns lots of them. Good for testing skinned mesh performance. Takes an unsigned integer argument for the number of foxes to spawn. Defaults to 1000
