Returning early if (wnd->parent && wnd->parent != GDW()) would avoid a
level of indentation here.

The GetMixMaxInfo fixup seems to occur with WS_MAXIMIZEBOX, should
that be taken into account? It might be cleaner to add a helper to
GetMinMaxInfo and here to combine these checks.

Any resason to move the PLACE_MAX before PLACE_MIN? It seems like an unnecessary change.
