static void *	btAlignedAllocDefault (size_t size, int alignment)
static void	btAlignedFreeDefault (void *ptr)
void	btAlignedAllocSetCustomAligned (btAlignedAllocFunc *allocFunc, btAlignedFreeFunc *freeFunc)
	If the developer has already an custom aligned allocator, then btAlignedAllocSetCustomAligned can be used. The default aligned allocator pre-allocates extra memory using the non-aligned allocator, and instruments it.
void	btAlignedAllocSetCustom (btAllocFunc *allocFunc, btFreeFunc *freeFunc)
	The developer can let all Bullet memory allocations go through a custom memory allocator, using btAlignedAllocSetCustom.
void *	btAlignedAllocInternal (size_t size, int alignment)
	we probably replace this with our own aligned memory allocator so we replace _aligned_malloc and _aligned_free with our own that is better portable and more predictable
void	btAlignedFreeInternal (void *ptr)

btAlignedAllocSetCustom()

void btAlignedAllocSetCustom	(	btAllocFunc *	allocFunc,
		btFreeFunc *	freeFunc
	)

The developer can let all Bullet memory allocations go through a custom memory allocator, using btAlignedAllocSetCustom.

btAlignedAllocSetCustomAligned()

void btAlignedAllocSetCustomAligned	(	btAlignedAllocFunc *	allocFunc,
		btAlignedFreeFunc *	freeFunc
	)

If the developer has already an custom aligned allocator, then btAlignedAllocSetCustomAligned can be used. The default aligned allocator pre-allocates extra memory using the non-aligned allocator, and instruments it.
