It is used in order change the widget stacking order in an inherited form for 
In ancestor form streaming- child- and creation-order is twidget1, twidget2, 
twidget3 what means (in MSEgui, I don't know for Lazarus) twidget2 is over 
twidget1, twidget3 is over twidget2.
Now you do 'Bring to Front' for twidget1 in a inherited form which changes the 
child order to twidget2, twidget3, twidget1.
The new child order must be written and read back while streaming the 
descendent. It is done with ffChildPos filerflag and a following integer.
Repositioning of the inherited children is done by  TComponent.SetChildOrder
