sheets in GNUstep

[Riccardo Mottola]

Hi,

I tried to enable sheets in GNUMail under GNUstep, that is, remove the 
"special GS code".
For save panel it works, however for a generic alert it does not.
I would expect a sheet to look and behave similar to an NSPanel, just 
modal to the window (like we fake drawers with a panel).

What I get however is a decoration-less, border-less panel with a 
different color.

I attach a screenshot.
