bcbe730471 Perform several rotation pertubations, to create multiple collision contact. works for convex versus plane. todo: convex versus convex. 
See issue http://code.google.com/p/bullet/issues/detail?id=20:

Note that the default number of pertubation iterations (10) and pertubation angle (0.05) can be modified through the collisionConfiguration:

	btConvexPlaneCollisionAlgorithm::CreateFunc* func = (btConvexPlaneCollisionAlgorithm::CreateFunc*)collisionConfiguration->getCollisionAlgorithmCreateFunc(BOX_SHAPE_PROXYTYPE,STATIC_PLANE_PROXYTYPE);
	func->m_numPertubationIterations = 0;
	func = (btConvexPlaneCollisionAlgorithm::CreateFunc*)collisionConfiguration->getCollisionAlgorithmCreateFunc(STATIC_PLANE_PROXYTYPE,BOX_SHAPE_PROXYTYPE);
	func->m_numPertubationIterations = 0;

0e3b04d952 Add COLLADA physics support for GImpact (allowing dynamic moving rigid bodies using concave collision shapes) in ColladaDemo, and ColladaConverter (import and export) 
Note: ColladaConverter will export a btGImpactConvexDecompositionShape the same as a btCompoundShape, so importing an exported btGImpactConvexDecompositionShape (roundtrip) creates a btCompoundShape

a8ec916af0 Added Height Field Fluid Demo to Bullet. All code stored in the Demos/HeightFieldFluidDemo directory for now. 
Please see HfFluidDemo.cpp for examples of how to use the height field fluid along with buoyant collision shapes.

The implementation is still lacking in my ways:
1) Need to complete more collision algorithms for buoyant collision shapes
2) Support compound buoyant shapes
3) The buoyancy model isn't that great
4) Fluid volume can be lost over time

6db1b932fd Make the btDbvtBroadphase deterministic/reproducable, by sorting the btBroadphasePair using unique ID, instead of proxy address. 
The btAxisSweep3 didn't suffer from this issue, because proxies were always allocated in-order, as part of an array.

65cdd7146f Use placement new for copy constructor of arrays. Thanks to M. Reuvers for the patch. 
http://bulletphysics.com/Bullet/phpBB3/viewforum.php?f=9

Generally, however, it is best to avoid copying entire arrays, but use a 
reference.

typedef btAlignedObjectArray<btSomeClass> Array;

Array a;
Array b = a;//avoid this whenever possible

This is much better:
Array& b = a;//use a reference
const Array& b = a; //or const reference
