Semi-transparent window parts can be done with BDirectWindow and special visible region calculation. No per-window compositing is needed.

Canāt a BBitmap be used as mask for the shape of the window? That would be similar to how arbitrary shapes are achieved on X.

I believe that was dockbert. I recall using it on r5.
True. There is an X terminal program that does transparency without compositor. Urxvt I think? It does this by taking a snapshot of the portion of the screen that it occupies, and renders that into its own frame. Pretty slick and lightweight. Works great in environments where you donāt drag windows around, like a tiling window manager, as the background snapshot would move with the window until it redraws upon placement.
Yes, there is just no easy to use API to do it. Itās not really a matter of complex implementation, just exposing it to apps in a convenient way.
