Fixes crashes due to rendering of softbody wireframe in the wrong thread (needs to be in 'debug' rendering section)

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.
Implement PyBullet.getCollisionShapeData
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

commandUid = 0

eb97e06280 fix minitaur.urdf: move lower-leg inertia to center, add missing collision for one of the motors, add contact parameters for friction_anchor, spinning friction, compliance (stiffness/damping)
fix in indexing for maximal coordinates (unused by default, still experimental, requires many iterations for Minitaur due to extreme mass-ratio, hence use of reduces/generalized coordinates)
modify quadruped.py to test maximal coordinates
wrap angular servo (positional) target within [-PI,PI] in btGeneric6DofSpring2Constraint
add 'j' key to show body frames in wireframe/debug mode

88897cc744 implement pybullet.changeTexture. For now, the width/height has to match the target texture unique id, otherwise crashes may happen (a check for width/height match will be added)

db008ab3c2 Improve debug text/line rendering, can be use to draw frames and text in local coordinate of an object / link.
example:
kuka = p.loadURDF("kuka_iiwa/model.urdf")
p.getNumJoints(kuka)
pybullet.addUserDebugLine([0,0,0],[0,0,0.1],[0,0,1],trackObjectUniqueId=2,trackLinkIndex=6)
pybullet.addUserDebugText("tip", [0,0,0.1],textColorRGB=[1,0,0],trackObjectUniqueId=2,trackLinkIndex=6)
Also allow to render text using a given orientation (instead of pointing to the camera), example:
pybullet.addUserDebugText("tip", [0,0,0.1],textColorRGB=[1,0,0],textOrientation=[0,0,0,1], trackObjectUniqueId=2,trackLinkIndex=6)
Add drawTexturedTriangleMesh, for drawing 3d text.
Expose readSingleInstanceTransformToCPU, to extract position/orientation from graphics index.
updateTexture: allow to not flip texels around up axis
