We subtract the screen space opaque region from the transformed surface region. That's going to fail for when we're scaling up a surface, since the surface bounding box for the scaled up surface is going to be bigger than the opaque region. Instead, subtract the surface-space opaque region from a 0,0 - width,height region and see if that's empty.
Weston Weston is the reference implementation of a Wayland compositor, and a useful compositor in its own right. Weston has various backends that lets it run on Linux kernel modesetting and evdev input as well as under X11. Weston ships with a few example clients, from simple clients that demonstrate certain aspects of the protocol to more complete clients and a simplistic toolkit. There is also a quite capable terminal emulator (weston-terminal) and an toy/example desktop shell. Finally, weston also provides integration with the Xorg server and can pull X clients into the Wayland desktop and act as a X window manager. Refer to http://wayland.freedesktop.org/building.html for buiding weston and its dependencies.
