Re: [1/2] windowscodecs: Implement GetPreview and GetThumbnail in the TIFF decoder.

According to MSDN, GetPreview isn't supported on any decoder except WMPhoto, and if that's true it should probably be returning WINCODEC_ERR_UNSUPPORTEDOPERATION. And why bother with GetThumbnail if you're not going to do it properly? At least check whether a thumbnail exists in the image before
