77c332bd88 PyBullet: add option to cache graphics shapes for URDF files, handy for benchmarks with many duplicate robots 
See https://github.com/erwincoumans/pybullet_robots ANYmal.py for an example.
PyBullet: Expose p.setPhysicsEngineParameter(solverResidualThreshold=1e-2) (b3PhysicsParamSetSolverResidualThreshold), increases solver performance a lot
PyBullet: Expose p.setPhysicsEngineParameter(contactSlop) Set it to zero, to avoid issues with restitution.
PyBullet: Expose isNumpyEnabled, return True is PyBullet was compiled with NUMPY support for 'getCameraImage'.
PyBullet: Expose p.ChangeDynamics(objectUid, linkIndex, contactProcessingThreshold), to avoid issues of speculative/predictive contacts with restitution.

85db288a95 App_PhysicsServer_SharedMemory_VR: expose max_num_object_capacity and max_shape_capacity_in_bytes (and shared_memory_key) 
Default values are:
int maxNumObjectCapacity = 128 * 1024;
int maxShapeCapacityInBytes = 128 * 1024 * 1024;
int shared_memory_key = -1

01f58f8f02 PyBullet: soft bodies are rendered, so we don't need to also render wireframes in regular mode. 
Use glBufferSubData instead of glMapBuffer/glUnmapBuffer, much faster soft body vertex sync.
Don't use a separate btSoftBodyWorldInfo, use the existing one in btSoftMultiBodyDynamicsWorld.

88b49947b5 Composite of fixed code for mingw64(on windows) and general fixes for msvc. 
1) (win32window) don't convert char to wide, use char direct to window.
2) (CMakeLists) Don't link one library as static CPPLIB and no others (mismatched allocations)
3) (macros) Fix Gwen macros for mingw64 on windows build.  (changes are by compiler(msc_ver) not platform)
4) (FileUtils) sprintf_s reference by platform, not compiler (mingw64 support)
5) (b3OpenCLUtils) fix bad define name _MSVC_VER->_MSC_VER
6) (compoundCollision) remove unused variables, simplify operation.
7) (impulseconstraint) remove duplicated code block

26d32f2aa8 improve loading performance of large textures: 
option to disable tinyrenderer, use p.configureDebugVisualizer(p.COV_ENABLE_TINY_RENDERER,0)
also make sure to use p.configureDebugVisualizer(p.COV_ENABLE_RENDERING,0) before loadURDF, and enable rendering afterwards using p.configureDebugVisualizer(p.COV_ENABLE_RENDERING,1)
reorder 2 loops, making the flip texels twice as fast (cache coherency),
single memcpy of entire texture in tinyrenderer, instead of per-pixel copy (memory layout is the same)
add lots of B3_PROFILE timings, to see where time is going
