/*++
* @name IDirect3DDevice9::Present
* @implemented
*
* The function IDirect3DDevice9Base_Present displays the content of the next
* back buffer in sequence for the device.
*
* @param LPDIRECT3D iface
* Pointer to the IDirect3DDevice9 object returned from IDirect3D9::CreateDevice().
*
* @param CONST RECT* pSourceRect
* A pointer to a RECT structure representing an area of the back buffer to display where
* NULL means the whole back buffer. This parameter MUST be NULL unless the back buffer
* was created with the D3DSWAPEFFECT_COPY flag.
*
* @param CONST RECT* pDestRect
* A pointer to a RECT structure representing an area of the back buffer where the content
* will be displayed where NULL means the whole back buffer starting at (0,0).
* This parameter MUST be NULL unless the back buffer was created with the D3DSWAPEFFECT_COPY flag.
*
* @param HWND hDestWindowOverride
* A destination window where NULL means the window specified in the hWndDeviceWindow of the
* D3DPRESENT_PARAMETERS structure.
*
* @param CONST RGNDATA* pDirtyRegion
* A pointer to a RGNDATA structure representing an area of the back buffer to display where
* NULL means the whole back buffer. This parameter MUST be NULL unless the back buffer
* was created with the D3DSWAPEFFECT_COPY flag. This is an opimization region only.
*
* @return HRESULT
* If the method successfully displays the back buffer content, the return value is D3D_OK.
* If no swap chains are available, the return value will be D3DERR_INVALIDCALL.
