099c36a71e Add a new flag btCollisionObject::CF_DISABLE_VISUALIZE_OBJECT to give control over what objects are drawn using the debug drawer
This solves Issue 238 , thanks to  Linzner for the suggestion
Remove some warnings from GL_DialogDynamicsWorld.

50a3c32a5f Added preliminary binary serialization code in btCollisionWorld.cpp, with example in Bullet/Demos/BasicDemo.cpp
(work-in-progress, some initial working version should be ready very soon, for Bullet 2.76)

c6df06c6a1 Added btDbvtBroadphase::setAabbForceUpdate to always update the aabb (skip optimizations), to address this issue (helps with occlusion culling)
///http://code.google.com/p/bullet/issues/detail?id=223

Also added a few missing 'virtual' keywords (the functions were virtual already because of the base class)

b57314c590 Added write access to implicitShapeDimensions, this allows to change the dimensions of a box, capsule etc.
See also request here: http://code.google.com/p/bullet/issues/detail?id=325

Also added a warning. This warning also applies to all methods that change the collision shape:

"changing a collision shape while the body is in the world is not recommended,
it is best to remove the body from the world, then make the change, and re-add it
alternatively flush the contact points, see documentation for 'cleanProxyFromPairs'"

fcd2b93a22 fix in box-box contact generation: choose better contact point location (along contact normal) when objects are swapped.
move debugDrawWorld to btCollisionWorld.
improved CollisionInterfaceDemo, show how to perform a closest point query for objects that are not in the collision world.

f65e829ca0 Add support for generic 2d convex shapes, through wrapper class btConvex2dShape. See Bullet/Demos/Box2dDemo for example wrapping a btCylinderShape and 2d btConvexHullShape.

3da9c832ae Initialize the world transform to identity for btCollisionObject/btRigidBody.
Some developers only initialize the world position, and not the orientation -> uninitialized data. 

We should probably add some warning in btTransform, in debug mode. Note we don't initialize btTransform/btQuaternion/btVector3/btMatrix3x3 default constructor, for performance reasons.

49a0b479c6 Switch off an optimization by default, to avoid support burden: update all objects AABBs and not just the active objects.
Call world->setForceUpdateAllAabbs( false) to re-enable the optimization: it will only update active objects (skipping static geometry)

aef97d6015 Share btGjkPairDetector, btGjkEpa2, btVoronoiSimplexSolver with SPU/Multithreaded implementation (remove duplicate code)
Make btTypedConstraint and btPersistentManifold both derive from btTypedObject to make SPU-side generic constraint solver easier.

Note: all build systems need to be updated: remove SpuVoronoiSimplexSolver.cpp, SpuGjkPairDetector.cpp, SpuEpaPenetrationDepthSolver.cpp, SpuGjkEpa2.cpp

3e2529fcb5 Minor constraint refactoring, to allow SPU-side processing for PLAYSTATION 3 (added non-virtual methods)
Also comment-out some code for __SPU__ to reduce code size
Added btContactConstraint (only used on PS3 SPU right now, better to use btPersistentManifold directly for contact constraints)
Improved readblend utility library (see also usage in http://gamekit.googlecode.com with Irrlicht)

40c73f327c + CMake build system fix under Windows: don't define _WINDOWS to allow Glut console demo to build properly
+ Allow user to enable useConvexConservativeDistanceUtil . Use dynamicsWorld->getDispatchInfo().m_useConvexConservativeDistanceUtil = true;
(see Demos/Benchmarks/Benchmark4 (convex objects falling down)
+ Fix for plane drawing (just wire-frame)
+ Gimpact: use collision margin of 0.07 for demo (because BULLET_TRIANGLE_COLLISION is used)
+ replace dot,cross,distance,angle,triple in btVector3 by btDot, btCross,btDistance,btAngle,btDistance to avoid naming conflicts
+ Some fixes in GJK penetration depth normal direction (broken in a previous commit)
+ fix in calculateDiffAxisAngleQuaternion to make ConvexConservativeDistanceUtil work properly
+ allow debug drawing to debug btContinuousConvexCollision
+ add comment/warning that btTriangleMesh::findOrAddVertex is an internal method, users should use addTriangle instead

If user wants more accurate inertia tensor for multi-sphere shape, use btCompoundShape instead 
(amd btCompoundShape::calculatePrincipalAxisTransform)
