That is a strange division of labor. I thought transparency and composition were aspects of window management. What else would they be?

Composition should be domain of display server, IMO (like with Xsgi). Windows DWM.EXE also, AFAIK, keeps to drawing not policy.

Transparency support falls under composition - the decision on applying the effect can be left to WM/app.

That's how world used to work, but it seems its going the way of dodo :-(
