82995a8343 pybullet, more robust multi-server connections
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

9ee1c4ec24 regular OR wireframe rendering, not both
add option to perform filtering of 'getClosestPoints' using linkA/linkB.
don't use 'realtimesimulation' as default
add/remove debug items within same thread
pybullet, report contact points and normal as [x,y,z] triplet/vector, not 3 scalars
separate 'getClosestPointsAlgorithm': box-box doesn't report closest points with positive distance, and the query shouldn't impact regular 'closesst points'

f9762d63ab Removed many memoryleaks in Example Browser, reducing some technical debt.
When running the Example Browser with Basic Example, 'visual leak detector' show no leak.
Many other individual examples still leak, so it is work-in-progress.
