This allows to render at a different machine, sending all assets across the TCP network, using port 6667 by default.
You can use ssh port forwarding to get this working:
ssh -R 6667:localhost:6667 username@remotehost.com -v
python3 -m pybullet_utils.graphicsServer
python3 -m pybullet_utils.graphicsClient
Note that there are still some tcp networking issues that can cause a hang, just restart graphics server and graphics client if it hangs.
use /tmp/timings on Linux/Mac as default location to save profile timings (when you press 'p' in example browser)
fix in Graphics Server Example when rendering is disabled
