I've already implemented in the same way (except the repaint forced
through the bool value, certainly useful in a pluggable cm as your).

I'm about to release mine too. It was an useful exercise, but I don't
belive useful coding a new composite manager.
Rather might be a good work porting to xcb an existing composite manager.
A composite manager take real advantage from xcb model and if kwin or
compiz (or *) developer are not devoted to an xcb port a new xcb cm is a
possibility.
