5b0253ed47 Remove undesired assert, it makes pybullet mistakes fail in c++
Shared memory api/pybullet: by default, set joint motors in position PD mode with target 0, to maintain 0 joint angle.
pybullet: allow setJointControlMode(body, link, POSITION_CONTROL,targetPos etc.

17c16ccfa0 pybullet, deal with overflow of joints (maximum of 128 joints/links per multibody at the moment)
increase from 64 to 128 joints in shared memory API/pybullet
fix potential issue in tinyrenderer, related to missing segmentation mask buffer
report error if CMD_REQUEST_ACTUAL_STATE command on a multibody that exceed the number of links,
todo: stream data to allow arbitrary large number of links in shared memory API

a9b1544a9f Add premake support to build pybullet, Windows and Linux tested, will enable Mac in next commit.
Expose inverse dynamics to Bullet shared memory API, through b3CalculateInverseDynamicsCommandInit and
b3GetStatusInverseDynamicsJointForces command/status. See PhysicsClientExeample or pybullet for usage.
Add option for Windows and Linux to set python_lib_dir and python_include_dir for premake and --enable_pybullet option
Expose inverse dynamics to pybullet: [force] = p.calculateInverseDynamics(objectIndex,[q],[qdot],[acc])
Thanks to Jeff Bingham for the suggestion.

c28cd03fbd OpenVR controller can pick/drag objects. Instructions, Windows only:
Compile using premake+visual studio, and compile App_SharedMemoryPhysics_VR
Compile pybullet using cmake using cmake -DBUILD_PYBULLET=OFF -DCMAKE_BUILD_TYPE=Release ..
Create a symbolic link from c:\python\dlls\pybullet.pyd to C:\develop\bullet3\cmp\lib\Release\pybullet.dll
App_SharedMemoryPhysics_VR
Run Python. Here are some Python lines to get going:
import pybullet as p
p.connect(p.SHARED_MEMORY)
p.loadURDF("cube.urdf")
p.setGravity(0,0,-10)
p.setRealTimeSimulation(1)

Allow real-time simulation in physics server, add pybullet command setRealTimeSimulation to control it
Mesh decimation (reduce number of triangles/vertices) using a Blender modifier for Kuka IIWA and Husky
Disabled the 'glFlush' commands in GLInstancingRenderer.
Add VR controller methods to examples\CommonInterfaces\CommonExampleInterface.h
Use the ANSI version in Windows file/string operations instead of unicode, hope this doesn't break builds.

Improve rendering performance. OpenVR experience is smooth now.

d0f20eafd1 Allow to build PhysicsServer in VR mode, to see the URDF/SDF robots in proper scale in VR.
Add option to have Z as up-axis for VR examples.
Add OpenVR LICENSE + README file
Don't crash VR app when no HMD is detected, just exit.
For now, don't request debug lines in client, it slows down physics server in VR mode too much.
