non-clipped child windows

[Cosmin Apreutesei]

Hi,

Does X have the notion of non-clipped child windows? The behavior in
WIndows and OSX for these is:

1) the parent always stays behind its children
2) the children are closed automatically when the parent is closed
3) the children follow the parent when moving

If the answer is no, then I can emulate 2 and 3 but how about 1?

Thanks,
Cosmin.
