I was thinking of just calling GetDesc() on the source surface and checking for D3DUSAGE_RENDERTARGET. I'm not sure that using StretchRect() / UpdateSurface() is that useful in practice, e.g. the default filter would disqualify both of them immediately.
As I understand filter (unlike color key) is not supposed to doanything if surface is not resized and pixel format is the same, and I believe it is rather frequent use case.
That's probably true.
Apart from that default filter is not currently supported (ignored with FIXME) in d3dx9 anyway, so it could continue to be not supported using a quicker StretchRect() for a time being without any functionality loss, while this would probably be not a nice solution.
Right, no, I'd rather not extend the hack further.
