Patch for window decoration

[Fred Kiefer]

Hi Alexander,

since you commited the patch to better support window decorations in 
GNUstep I sometime get display problems when resizing a GNUstep window.

I am using KDE 3.2.1 on a SuSE Linux 9.1, the xlib backend of GNUstep 
and I don't have the new decoration implementation switched on.

The problems can be seen in the GSTest applciation by resizing the 
colour well. Here sometimes an area of the window will stay white.

Cheers
Fred
