7e4dfb7207 remove SimpleOpenGL3 demo, it breaks some builds
reset callback to 0 after exiting a demo to avoid issues

6c9bfce975 Support btMultiBody soft contact using ERP and CFM. Also support custom relaxation parameter to allow successive over relaxation.
Added demos for rigid and multi body soft (compliant) contact.
Will also add simplified Hertz compliant contact, by dynamically modifying the ERP/CFM to mimic a non-linear spring.
Note that btManifoldPoint is growing too big, we need to implement proper contact constraints derived from btTypedConstraint.

6bc3f94f52 add a Pendulum example that is also used as unit test.
Gold data is created by numerically solving a second-order non-linear differential equation.
(see examples/MultiBody/pendulum_gold.h)

2920d7e61f Only support btMultiBody multi-dof version (remove non-multi-dof path)
Use ATTRIBUTE_ALIGNED16 for btMultiBody
Always disable parentCollision for btMultiBody::setupFixed

081a40d254 initial implementation to send debug lines from physics server to client,
need to add streaming because memory is too small to store all lines
initial test of PD control in physics server, need to switch to PD control for motor constraint, instead of using external forces.

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

f6f76901fd First draft of btMultiBody serialization, including optional names for base, link and joints (see ImportURDFDemo/ImportURDFSetup.cpp how this is done)
Bump up version number to 2.84 because of new serialization data.

d830681674 add option for rigid body/typed constraint to set target velocity
compare joint feedback between multi body and rigid body. initial results are promising (not exactly the same, but reasonably close)

89edc40d61 First step in btMultiBody joint force/torque feedback. There is still some work to be done for 'mobilizer limit/motor'.
See examples/MultiBody/TestJointTorqueSetup and examples/Constraints/TestHingeTorque for joint feedback.

218e9f9bf9 enable URDF loading throught the 'File/Open' menu
set a default camera targets for each demo. note that it is only reset when switching to a different demo, so you can restart at your chosen location.
no OpenCL pairbench drawing in OpenGL2 (there is no VBO available etc)
