cairo: replace cairo with pixman in decos, particles and modules

Browse source 
All decoration, particle and module interfaces now takes a
pixman_image_t parameter, and all drawing is done using pixman APIs.

The wayland/xcb backends implement a new interface functions,
get_pixman_image(), that should return a pixman image instance that is
suitable for rendering.

In the wayland backend, the image uses the same backing data as the
cairo surface.

In the XCB backend, we create a new image each time, and then blit it
to the cairo surface at commit time.
