erwincoumans 8c69fa13ca add pybullet getCameraImage, replacing renderImage, cleaner API:
always pass in width, hight and viewMatrix, projectionMatrix, optionally lightDir
added helper methods computeViewMatrix, computeViewMatrixFromYawPitchRoll, computeProjectionMatrix, computeProjectionMatrixFOV
see Bullet/examples/pybullet/testrender.py + testrender_np.py for example use
add missing base_link.stl for husky.urdf
