Bug#433073: Please disable DirectFB's window backend buffer

[Attilio Fiandrotti <attilio.fiandrotti@gmail.com>]

package: rootskel-gtk
severity: wishlist
tags: patch

DirectFB allows to set [1] the way the desktop window buffering 
mechanism works by disabling the backend buffer.
The result, in my experiments, was saving some some hundreds KB of 
memory with no noticeable drawbacks.
I propose to apply the attached one-line patch and look for possible 
artifact which may appear on the display, and in the case reverse the patch.

regards

Attilio
