68f798a2da Start re-organizing demos so the physics setup can be shared easier (explicit create graphics objects, init/exit physics etc) 
Add B3G_RETURN key code, only implemented in Windows so far (todo: Mac, Linux)
Fix Windows key management (use WM_CHAR event instead of WM_KEYUP
Add Return (OnKeyReturn) key support TreeNode, so we can select an item using the return key.

c782f4976c Various minor PLBVH related changes. 
-Use most significant bit instead of negative for internal nodes.
-Explicitly store root node index, so that it does not have to be 0.
-Check the root node first in PLBVH traversal.
-Fix rigid body clipping in RaytracedShadowDemo.

3e8b183587 Avoid breaking up the clipHullHull kernel, it ruins performance. Unfortunately, Mac OSX still requires it. 
Use indices instead of copies for small/large aabbs in broadphase (grid / sap)

71f0537c6e add Bullet 2.x constraint solver tests for hinge, with large mass ratio 
experiment with Midi controls in PairBenchmark to tune variables (will move it into a utility class, so every demo can easier use it in the future)

472a4068fc Enable MPR by default 
Add the contact point from MPR, in addition to SAT/clipping contacts. Added a new kernel to clear/reset the number of contacts in pairs (stored in the z component)
Always sample unit sphere directions, if there are more edge-edge combinations than unit sphere directions (162 by default)

2e55d03fd9 more fixes towards working convex-convex, in case of (too) many edge-edge cases: 
1) sample directions over a unit sphere and
2) add a contact, using mpr

271f458837 Ported Minkowski Portal Refinement mpr.c from libccd to OpenCL, for bettwe edge-edge performance (and additional contact point for degenerate/high detailed convex shapes)

5ce0b3938f Re-introduce GPU parallel Jacobi solver, called btGpuJacobiContactSolver. There are still some issues, but for basic scene's it works. 
To avoid confusion, rename GPU contact solver to btGpuContactSolver, and constraint (non-contact) solver to btPgsConstraintSolver.
