Thank you.

Beryl has support for getting thumbnails of windows when they're
unmapped. When a window is unmapped, the pixmap is saved. Look at the
code: http://glug.grm.hia.no/beryl/trunk/beryl-core/src/window.c
(search for 'thumbTexture' and 'thumbPixmap').
Do you have any plans to add support for this in Compiz core too?
