f0528db5e9 embed V-HACD directly into Pybullet to make it easier to use:
pip3 install pybulle
import pybullet as p
p.connect(p.DIRECT)
p.vhacd("teddy.obj", "teddy_large_newout.obj", "newlog.txt", depth=2,resolution=1000000)

6afa0a463d unsupported: expose collisionMargin to changeDynamics/getDynamicsInfo.
add cube_convex.urdf for testing this collisionMargin. Test script:
import pybullet as p
import time
p.connect(p.GUI)
plane = p.loadURDF("plane_implicit.urdf")
cube = p.loadURDF("cube_convex.urdf",[0,0,1])
p.setGravity(0,0,-10)
while (1):
	p.stepSimulation()
	pts = p.getContactPoints()
	p.changeDynamics(plane,-1,collisionMargin=0.3)
	p.changeDynamics(cube,-1,collisionMargin=0.3)
	print("===================")
	print("cube pos=", p.getBasePositionAndOrientation(cube)[0])
	print("margin=", p.getDynamicsInfo(plane,-1)[11])
	#time.sleep(1./10.)

7263439c4b improved for inserting profile timings from Python, to analyzer performance of pybullet programs.
See examples/pybullet/examples/profileTiming.py for an example. Note that python and c++ is properly interleaved.
Open a timings with a name, close the timing without a name. Note that timings can be recursive, added/popped as a stack.

ed4515ae17 for the GraphicsServer, expose a sync transform interval: only synchronize the transform once the stepSimulation exceeds this time interval.
(for example, run the simulation at 1kHz but sync the graphics transforms to remove graphics server at 30Hz)

c3b7f39aaf expose shadowMapResolution (texture resolution) and shadowMapWorldSize (size in meters in world space)
expose pybullet.ConfigureOpenGLVisualizerRequest(lightPosition=[x,y,z], shadowMapWorldSize=10.5, shadowMapResolution=16384)
See examples/pybullet/examples/configureDebugVisualizer.py for an example.
This reimplements https://github.com/bulletphysics/bullet3/pull/2295 but without creating a new command/status and explicitly referring to the debug visualizer
(since the 'getCameraImage' also has a lightPosition)
