4d6741f5cd PyBullet: expose STATE_LOGGING_ALL_COMMANDS and STATE_REPLAY_ALL_COMMANDS
See examples/pybullet/examples/commandLogAndPlayback.py for an example.

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).

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.

e5a9b42f9a expose PyBullet.setPhysicsEngineParameter(jointFeedbackMode)
use p.JOINT_FEEDBACK_IN_JOINT_FRAME if you want the joint feedback expressed in joint frame (instead of link inertial frame)
use p.JOINT_FEEDBACK_IN_WORLD_SPACE if you want the joint feedback in world space coordinates, instead of local link/joint coordinates.
Example: p.setPhysicsEngineParameter(jointFeedbackMode=p.JOINT_FEEDBACK_IN_WORLD_SPACE+p.JOINT_FEEDBACK_IN_JOINT_FRAME)

b578361acf Use kF_UseGjkConvexCastRaytest by default for raycast in PyBullet (it is more robust/accurate, but a bit slower)
Use 10*EPSILON, as suggested in Gino's paper:

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.

22b4809891 leave m_useGlobalVelocities to false, until enabled, for backward compatibility
use URDF_GLOBAL_VELOCITIES_MB flag in PyBullet loadURDF.
fix robot_bases.py due to new fields in getJointInfo.
backward compabitibility: BulletMJCFImporter, keep creating btMultiSphereShape for MJCF capsules with fromto, instead of shifted btCapsuleShapeZ, unless if CUF_USE_IMPLICIT_CYLINDER is used.
