Question xfbd - gtk2 version

[Jasper Huijsmans]

Hi Olivier,

I have now a working version of xfbd for GTK2. I have two questions
regarding things I did differently than in the current version.

First, when you set the XProperty on the pixmap you use a copy of the
pixmap. Is this necessary? It seems to work for me without it.

Second, is there a good reason for the 'clear' button? It doesn't seem
very useful. If you don't want a backdrop, don't run xfbd.
