winPaintInverse corresponds to the old ScrOperation value scrCopyNOT. I don't see that this is supported for scrolling operations before 4.0 (even if the x/y deltas are zero). That is, I don't see it supported in 3.3 or 3.5. However, 3.5 has the benefit of actually telling you that it's not supported.
