bullet3/examples/Importers/ImportBullet/SerializeSetup.cpp
Erwin Coumans 26531f3fbc fix some warnings, disable gimpact by default in world importer,
use DIRECTLY_UPDATE_VELOCITY_DURING_SOLVER_ITERATIONS by default for now,
until we find the issue with some failing test cases in btMultiBody
fix a crashing issue in MyMultiBodyCreator.cpp (uninitialized variable)
disable excessive debug printf in URDF2Bullet
