Windows and content frame

[Riccardo Mottola]

Hi,

I ported GMastermind to the Mac. It generates its windows and palettes 
from code which is 100% shared between the gnustep and cocoa version.

Look:

Do you see that on the mac there is a white space below the tile bar and 
the window content? It is especially evident in the "Palette" window.

I fear we are doing "good" while we should not.

I tried enabling and disabling native window decorations (being 
suspicious that the white space appears to be the window title bar 
height) but no change.
