Yes, i first tried to use an existing compositing manager, but the
problem is that only a few do a fade on some windows (and not on all
the windows), and those who do what I would like to are not compatible
with ratpoison (Cairo Composite Manager does not work with ratpoison,
i've got a black screen, and when ratpoison tries to Map/Unmap a
window, the screen is blinking instead of fading, then the black
screen reappears...)


Anyway, i'm trying to understand how cairo composite manager works, to
try to know how to use XRender/XComposite/Cairo.
