0e8bc418d7 add utility for reading and writing of minitaur quadruped robot log files.
Example usage:
const char* fileName = "D:/LOG00053.TXT";
btAlignedObjectArray<MinitaurLogRecord> logRecords;
btAlignedObjectArray<std::string> structNames;
std::string structTypes;
bool verbose = false;
//reading
int val = readMinitaurLogFile(fileName, structNames, structTypes,
logRecords, verbose);

//writing
const char* fileNameOut = "D:/LOG00100.TXT";
FILE* f = createMinitaurLogFile(fileNameOut,structNames,structTypes);
for (int i=0;i<logRecords.size();i++)
{
  appendMinitaurLogData(f, structTypes, logRecords[i]);
}
closeMinitaurLogFile(f);

26a34e3cda Move ChromeTracing in its own file, and add tracing support for VR server (App_SharedMemoryPhysics_VR)
Add a bit of extra sleep in PhysicsServer thread, to make rendering smoother.

5e6cfd70b5 iOS platform and Android don't have __thread local storage, so avoid multi-threaded profiler on those (only on _WIN32, __linux__ and __APPLE__ and not TARGET_OS_IPHONE
Add a Sleep(0) for Windows to yield threads (and not Sleep(1))

4c06fd27b3 Example Browser: add option (keypress 'p') to dump json timing profile trace, that you can open using Chrome about://tracing
Make btQuickprof thread safe
Add option in btQuickprof to override custom timing profile (btSetCustomEnterProfileZoneFunc, btSetCustomLeaveProfileZoneFunc)
remove b3Printf in a user/physics thread (those added added, while drawing the GUI running in the main thread)

f0f694145d Implement TimeWarpBase.
-------------------------------------
This commit implements speeding up and slowing down examples. The
example can be influenced by the parameters. A separate example will be
added to show off the capabilities of the TimeWarpBase for other
examples. 

The walkers work quite well, a successful evolution was run over night
and reached a walker distance of 7.2m.

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.

02582e3a78 shrink down cube size of BasicDemo 10 times (it looked ginormous in VR) from 2x2x2 meter to 0.2
add test for VR HUD/sub-titles
fix issue in previous commit, partial string use %.8s not %8.s
use long long int in b3Clock
fix warning/error in pointer alignment in serialization
Fix pybullet Windows compilation.

06d6c9fc3a There was a typo I came across when cross compiling
TLDR; I fixed a typo for the windows build.
