System::Init

static SF_EXPORT void SF_CDECL Init(const MemoryHeap::HeapDesc& rootHeapDesc, SysAllocBase* psysAlloc = SF_SYSALLOC_DEFAULT_CLASS::InitSystemSingleton());
static SF_EXPORT void SF_CDECL Init(SysAllocBase* psysAlloc = SF_SYSALLOC_DEFAULT_CLASS::InitSystemSingleton());
static SF_EXPORT void SF_CDECL Init(SysAllocBase* psysAlloc = SF_SYSALLOC_DEFAULT_CLASS::InitSystemSingleton());

Init initializes System core, setting the global heap required for GFx memory allocations. This method is called first before any GFx objects are instantiated. Two methods are provided to allow specifying SysAllocBase with and without MemoryHeap::HeapDesc for the root heap. Users can override memory heap implementation by passing a different memory heap here.
