Windows shared memory: allow to use custom key. Improve GUI performance on Windows, submit letters in text as a batch (fewer draw-calls) quadruped.py: first try to connect to SHARED_MEMORY, if it fails (<0) use GUI increase Chrome about://tracing json export capacity (press 'p' in Example Browser) UDP physics server: add --port and --sharedMemoryKey command-line arguments PhysicsServerExample: add --sharedMemoryKey command-line option (for VR example too) ExampleBrowser: sleep a few milliseconds if rendering is too fast, use --minUpdateTimeMicroSecs=0 to disable
