badf723257 Replace all hardcoded 1e30(f) by BT_LARGE_FLOAT, defined in btScalar.h as 1e18(f) so that its square still fits in FLT_MAX

fb6146f0be Added MiniCL, a limited subset of OpenCL, the open standard for parallel programming of heterogeneous systems. 
MiniCL includes a cross-platform run-time frontend based on pthreads, Win32 Threads, or libspe2 for Cell SPU.
It is there, to bridge the gap until OpenCL is more widely available.

See Bullet/Demos/VectorAdd, influenced by NVidia OpenCL Jumpstart Guide:

2f1014268b + Internal improvements for collision shapes 
1) add AabbCaching versions of btPolyhedralConvexShape and btMultiSphereShape (this speeds up btMultiSphereShape 'getAabb', and reduces size of btBoxShape)
2) btCylinderShape doesn't derive from btBoxShape anymore
+ Minor fixes in drawing for btMultiSphereShape, btBoxShape.
+ Don't re-generate btDebugFont every frame
+ Disabled velocity prediction for btDbvtBroadphase. Previous default can be restored using btDbvtBroadphase->setVelocityPrediction(1./2.);

42ece54556 applied patch that allows to enable multithreading mode for CcdPhysicsDemo, 
Still requires manually adding BulletMultiThreaded library dependency (we won't enable it by default just yet)

erwin.coumans
700db838b1 Add 1D and 2D support for Bullet: using rigidbody->angularFactor(const btVector3& factor) and body->setLinearFactor(const btVector3& linearFactor); 
For example, to only allow linear motion in the X-Z plane, and only rotation around Y axis use:
	body->setLinearFactor(btVector3(1,0,1));
	body->setAngularFactor(btVector3(0,1,0));
Fix build issues with CodeBlocks, when generating projectfiles using CMake 2.6:
${OPENGL_glU_LIBRARY} should be ${OPENGL_glu_LIBRARY}
Fix build issue with CodeBlocks, comment out xmlfree in Extras/COLLADA_DOM/src/modules/LIBXMLPlugin/daeLIBXMLPlugin.cpp (will leak memory)

90f96aec27 Introduced btActionInterface. This makes it easier to extend user-defined actions, such as vehicles and characters. 
btRaycastVehicle and btKinematicCharacterController are derived from btActionInterface now.
Some cosmetic cleanup: changed sourceforce/sf.net url to bulletphysics.com.

Use btAssert and not assert.
Don't access btAlignedObjectArray elements, for zero sets

Fix Dynamica MayaPlygin: remove 'active' flag, it has to be replaced by mass=0 for active, mass<>0 for passive
Added missing projectfiles
Fixed single-shot contact generation. it is disabled by default to improve performance
Bugfixes for character controller, thanks to John McCutchan for reporting
Constraint solver: better default settings
btDefaultAllocator: aligned allocator uses non-aligned allocator (instead of directly malloc/free)

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
