[This was originally a workaround for a client-side resource leak: http://lists.freedesktop.org/archives/xorg-devel/2012-November/034555.html Obviously that's a broken app, but the performance problem it illustrates - that walking the linked list ends up burning all your CPU time - is real enough. - ajax] v2: Replace with a shorter code sequence which computes the same results for all but numBits == 7 Reviewed-by: Adam Jackson <ajax@redhat.com> Signed-off-by: Keith Packard <keithp@keithp.com>
X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
