5bcd43711a PyBullet OpenGL/EGL hardware getCameraImage: use glViewport to reduce the glReadPixels calling cost dramatically for small images
PyBullet Allow OpenGL/EGL hardware to render segmentation mask. Use pybullet.ER_SEGMENTATION_MASK_OBJECT_AND_LINKINDEX or pybullet.ER_SEGMENTATION_MASK
PyBullet.removeBody fix indexing bug (use foundIndex, not i)
PyBullet bump up version to 2.2.3

ab8f16961e Code-style consistency improvement:
Apply clang-format-all.sh using the _clang-format file through all the cpp/.h files.
make sure not to apply it to certain serialization structures, since some parser expects the * as part of the name, instead of type.
This commit contains no other changes aside from adding and applying clang-format-all.sh

9553892770 PyBullet / BulletRobotics:
Implement collisionFilterPlugin, use setCollisionFilterPair to enable or disable collision detection between specific pairs of objects.
Also, expose setCollisionFilterGroupMask as PyBullet API and in urdf using the tag <collision group="1" mask="2"/>.
See examples/pybullet/examples/collisionFilter.py for an example.
PyBullet default: Lower the warmstarting factor, for maximal coordinates rigid bodies for more stable simulation.
Add btCollisionWorld::refreshBroadphaseProxy to easier recreate the broadphase proxy without adding/removing objects to the world.

ee9fca8c29 GJK fix for https://github.com/bulletphysics/bullet3/issues/1703
In a nutshell, we added a more reliable check, based on if the origin is in the GJK simplex, to determine if we are really intersecting and need to run EPA.
See also "Real-time Collision Detection with Implicit Objects" by Leif Olvang
Todo: integrate the simplex penetration check directly inside the Bullet btVoronoiSimplexSolver
and remove this temporary code from libCCD
Note, for large differences in shapes, use double precision build!

f2afb4af35 remove some debug globals from third_party/bullet
There are some debug global variables that prevent using bullet safely on multi-threaded environments (tsan failures).

97c6937388 Simplify GJK. Still needs double precision for large differences of feature scales.
Extract faces directly from btConvexHullComputer (in initializePolyhedralFeatures), instead of reconstructing them, thanks to Josh Klint in #1654
PyBullet: use initializePolyhedralFeatures for convex hulls and boxes (to allow SAT)
PyBullet: expose setPhysicsEngineParameter(enableSAT=0 or 1) to enable Separating Axis Test based collision detection for convex vs convex/box and convex versus concave triangles (in a triangle mesh).

b578361acf Use kF_UseGjkConvexCastRaytest by default for raycast in PyBullet (it is more robust/accurate, but a bit slower)

0326fa93a8 made some progress in saving and restoring the state during the simulation, with identical results.
Option to de/serialize btPersistentContactManifolds and fix lossy conversion during btMultiBody de/serialization of base world transform
(serialize the quaternion, not the converted 3x3 matrix)
There are still several caches not taken into account, and btMultiBody links/constraints are not deserialized yet etc.
See examples\pybullet\examples\saveRestoreState.py for an example.
