To be honest I do not do anything to get the preview of any windows. I
use the library Clutter (or Cogl to be more precisely) which does all
the work for me. That was also the decision to use Clutter 3 year ago
when I started developing xfdashboard.
Nowadays I know I could get these previews also with XComposite,
XDamage, XRender and so on. If you want to avoid a big library like
Clutter/Cogl or OpenGL at all then consider to have a look how skippy-xd
gets the previews. But these are still images and not live updated like
