HRESULT WINAPI D3DXCreateTextureFromFileEx(          LPDIRECT3DDEVICE9 pDevice,
    LPCTSTR pSrcFile,
    UINT Width,
    UINT Height,
    UINT MipLevels,
    DWORD Usage,
    D3DFORMAT Format,
    D3DPOOL Pool,
    DWORD Filter,
    DWORD MipFilter,
    D3DCOLOR ColorKey,
    D3DXIMAGE_INFO *pSrcInfo,
    PALETTEENTRY *pPalette,
    LPDIRECT3DTEXTURE9 *ppTexture
);
使用它创建纹理里，    DWORD Filter,DWORD MipFilter,这两个参数用来设置过滤，只要将它们都设为D3DX_FILTER_NONE就可以不过滤了，记住，这样的话，图片一定要是2^n大小
