Before, cairo-util.h would combine pixman and cairo includes. X11 and Wayland compositors uses this to load an image as a pixman_image_t but are forced to include cairo headers. Clients use load_cairo_surface to load images as cairo_surface_t's, but are forced to include pixman.h. We move the load_image pixman prototype to its own header, so compositors can get at the pixman prototype without including cairo.h and clients can include the cairo based function without including pixman.h.
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.
