D3DXLoadSurfaceFromSurface sample

[walbourn]

DirectXTex has all the facilities needed to support the old 'load-surface-from-surface' behavior. A sample implementation would help those porting D3DX code as well as demonstrate how heavy-weight that function was:

HRESULT WINAPI
    D3DXLoadSurfaceFromSurface(
        LPDIRECT3DSURFACE9        pDestSurface,
        CONST PALETTEENTRY*       pDestPalette,
        CONST RECT*               pDestRect,
        LPDIRECT3DSURFACE9        pSrcSurface,
        CONST PALETTEENTRY*       pSrcPalette,
        CONST RECT*               pSrcRect,
        DWORD                     Filter,
        D3DCOLOR                  ColorKey);

HRESULT WINAPI
    D3DXLoadVolumeFromVolume(
        LPDIRECT3DVOLUME9         pDestVolume,
        CONST PALETTEENTRY*       pDestPalette,
        CONST D3DBOX*             pDestBox,
        LPDIRECT3DVOLUME9         pSrcVolume,
        CONST PALETTEENTRY*       pSrcPalette,
        CONST D3DBOX*             pSrcBox,
        DWORD                     Filter,
        D3DCOLOR                  ColorKey);

HRESULT WINAPI
    D3DX11LoadTextureFromTexture(
	ID3D11DeviceContext       *pContext,
        ID3D11Resource            *pSrcTexture,
        D3DX11_TEXTURE_LOAD_INFO  *pLoadInfo,
        ID3D11Resource            *pDstTexture);
