I'm not entirely sure on how to do this properly. Making it an ERR
would be too loud for applications that never use s3tc textures, as a
WARN it's never going to be seen unless you look at the debug channel.
Printing a message in wined3d in CreateSurface() would probably work,
but the resulting check would end up being pretty ugly because we'd
have to check 5 different formats. You can't do much more than a WARN
for a generic check either, because some formats may be legitimately
missing / unimplemented. Note that the situation with floating point
formats isn't much better.
