* Not called from the VTable
*
* Some older interface versions operate with handles, which are basically
* DWORDs which identify an interface, for example
* IDirect3DDevice::SetRenderState with DIRECT3DRENDERSTATE_TEXTUREHANDLE
*
* Those handle could be just casts to the interface pointers or vice versa,
* but that is not 64 bit safe and would mean blindly derefering a DWORD
* passed by the app. Instead there is a dynamic array in the device which
* keeps a DWORD to pointer information and a type for the handle.
*
* Basically this array only grows, when a handle is freed its pointer is
* just set to NULL. There will be much more reads from the array than
* insertion operations, so a dynamic array is fine.
*
* Params:
* This: D3DDevice implementation for which this handle should be created
*
* Returns:
* A free handle on success
* 0 on failure
