Semi -transparent windows

[Alexei Babich]

Maybe you can suggest how to get pixmap, containing a complete picture under a window w3 (ie, parts of the {w1, w2, root}, according to their location at the moment), in accordance with the scheme? If I can get this pixmap, it part can be used as a source for the image of a window w3, for creating semitransparent.

Thank you.
