Window previews in xfwm4

[Sonal Santan]

Hello,

I have an early version of window previews working. With ALT-TAB, tabwin
shows snapshot of all windows including ones which are minimized. For the
latter it uses cached snapshot which was saved just before the window was
minimized. I am working on flushing out the bugs and hope to submit my
patches to the mailing list for review soon.
