BehaviorFlags —Specify either D3DCREATE_HARDWARE_
VERTEXPROCESSING or D3DCREATE_SOFTWARE_VERTEX-
PROCESSING for this parameter

pPresentationParameters —Specifies an initialized
D3DPRESENT_PARAMETERS instance that defines some of the
characteristics of the device

Example call:
IDirect3DDevice9* device = 0;
hr = d3d9->CreateDevice(
D3DADAPTER_DEFAULT, // primary adapter
D3DDEVTYPE_HAL, // device type
hwnd, // window associated with device
D3DCREATE_HARDWARE_VERTEXPROCESSING, // vertex processing type
&d3dpp, // present parameters

&device); // returned created device

if( FAILED(hr) )
