unity's restore from maximize is breaking the positioning of overlay thumb

[Andrea Cimitan]

after restoring from a maximized window, thumb is misplaced, you need to do a configure event like a resize in order to place it correctly.
does not happen without unity, does not happen with metacity

Figured out what's going on... it's a smspillaz's question.
So, you know unity is removing the titlebar on maximize, but after restoring the titlebar is added "after" the configure-event, so event->x and event->y of the configure event connected to the scrollbar lack of the pixels of the titlebar (and the scrollbars are higher of the amount of pixels of the titlebar)

After a long discussion with jason, it seems his bug is a way harder than it seems, and maybe long to fix.
We need to connect to the parent window of the toplevel window, which is a xwindow, create a gdk_x11_foreign window and hook up for its configure_event.
This is the hardest part, because adding a filter_func for each scrollbar (so, twice the filter func for each scrollbar), is a terrible idea. we should try to figure out a way to connect to a global filter func that tells each scrollbar to update the window coordinates when the xconfigureevent of the parent window of its toplevel window is received. (please kill me :-\)
