bf9efffa4b Increase mesh allocation for vertices/indices in PyBullet.createCollisionShape 
See createMesh.py for an example.

The data has to fit in shared memory, hence the limit on Mac is lower than Windows and Linux:

#ifdef __APPLE__
#define B3_MAX_NUM_VERTICES 8192
#define B3_MAX_NUM_INDICES 32768
#else
#define B3_MAX_NUM_VERTICES 131072
#define B3_MAX_NUM_INDICES 524288
#endif
