1) (win32window) don't convert char to wide, use char direct to window.
2) (CMakeLists) Don't link one library as static CPPLIB and no others (mismatched allocations)
3) (macros) Fix Gwen macros for mingw64 on windows build. (changes are by compiler(msc_ver) not platform)
4) (FileUtils) sprintf_s reference by platform, not compiler (mingw64 support)
5) (b3OpenCLUtils) fix bad define name _MSVC_VER->_MSC_VER
6) (compoundCollision) remove unused variables, simplify operation.
7) (impulseconstraint) remove duplicated code block
add option to perform filtering of 'getClosestPoints' using linkA/linkB.
don't use 'realtimesimulation' as default
add/remove debug items within same thread
pybullet, report contact points and normal as [x,y,z] triplet/vector, not 3 scalars
separate 'getClosestPointsAlgorithm': box-box doesn't report closest points with positive distance, and the query shouldn't impact regular 'closesst points'
add rolling/spinning friction to cube, remove it from plane/samurai.urdf
URDF2Bullet: support joint limits for revolute and prismatic, only if defined (if upper < lower, disable limit)
add some profiling markers to improve performance
with hash pair caching and tandem tree traversal. It should be much faster, when using many child shapes for both compounds.
Fix iOS compilation, added header.
