bullet3/examples/SharedMemory/PhysicsServerExample.cpp
Erwin Coumans 433d11d8cf Add a btIDEbugDraw::clearLines, helps multi-threaded rendering of lines (while updating those lines in a dynamics world in a different thread)
Expose COV_ENABLE_VR_RENDER_CONTROLLERS, to enable/disable rendering of controllers (and some frames) in VR
Expose COV_ENABLE_RENDERING to enable/disable rendering.
Fix some multi-threading issues (potential crashes), related to debug drawing/rendering in one thread, while changing the dynamics world/removing/resetSimulation in a different thread.
