OpenGL render plugin

63f4a63e15 since parent collision is always disabled by default for self-collision, we add a new flag 
URDF_USE_SELF_COLLISION_INCLUDE_PARENT, to force self-collision between direct parent/child (not recommended in general)

ff43cea263 Fix some deactivation issues with btMultiBodyDynamicsWorld, should also improve performance for PyBullet with larger worlds

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.

552cb5852a PyBullet: add signed distance field support, with example/signedDistanceField.py 
See also data\toys\concave_box.urdf and data\toys\concave_box.cdf

data\toys\concave_box.cdf was generated from concave_box.obj using
//GenerateSDF.exe -r "32 32 32" -d "-1.6 -1.6 -.6 1.6 1.6 .6" concave_box.obj
//SDF is based on code from DiscreGrid, https://github.com/InteractiveComputerGraphics/Discregrid

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)

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.

79d78a325a Start of a urdfEditor.py, limited support to extract a URDF from a PyBullet body. 
Use btCylinderShapeZ for URDF cylinder, instead of converting it to a btConvexHullShape.

Extend PyBullet.getDynamicsInfo / b3GetDynamicsInfo, remove flag (don't rely on API returning a fixed number of elements in a list!)
Extend PyBullet.getJointInfo: add parentIndex
