The test I mentioned is not meant for the Wine test suite (even though
it would be nice to have some kind of Wine test eventually). You would
write a standalone application (or hack something in the d3dx9 tests,
it might be easier) along the lines of what I described and run it
against native d3dx9_36.dll, ideally on Windows. You'd save the
filtered images and eyeball them to try to figure out what's the
filtering algorithm used by MS. I have no idea whether it will be
doable in practice or not but it seems worth a try.
