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.

ddf304ca78 PyBullet: expose internal edge utility, to adjust edge normals to prevent object penetrating along triangle edges of concave triangle meshes
(due to local convex-triangle collisions causing opposite contact normals, use the pre-computed edge normal)

This reverts commit d2d987a5ed.

After discussion, we decided to use userPtr.

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.
