This has multiple effects:
1) The i3 codebase is now consistently formatted. clang-format uncovered
plenty of places where inconsistent code made it into our code base.
2) When writing code, you don’t need to think or worry about our coding
style. Write it in yours, then run clang-format-3.5
3) When submitting patches, we don’t need to argue about coding style.
The basic idea is that we don’t want to care about _how_ we write the
code, but _what_ it does :). The coding style that we use is defined in
the .clang-format config file and is based on the google style, but
adapted in such a way that the number of modifications to the i3 code
base is minimal.
_NET_ACTIVE_WINDOW:
> The window ID of the currently active window or None if no window has
> the focus.
This fixes a bug that would not update _NET_ACTIVE_WINDOW when focus
changed to an i3 container without a window such as a branch or
workspace content container.
This patch adds a new configuration option "mouse_warping [output|none]".
When mouse warping is disabled, mouse cursor does not jump to middle of current
screen when changing workspaces between multiple outputs. This introduces a
"special" cursor state, where focus is in one window and cursor on another.
Useful for eg. scrolling a web page with mouse wheel while typing into another
window on keyboard.

The _NET_CLIENT_LIST property of the root window:
> These arrays contain all X Windows managed by the Window Manager.
Dock clients are not managed windows, so they should not be included in
_NET_CLIENT_LIST or _NET_CLIENT_LIST_STACKING.
If input focus is set by the window manager, it is not necessary to send
WM_TAKE_FOCUS because it has already taken focus.

Both setting input focus and sending WM_TAKE_FOCUS is effectively
setting focus on the window twice which is certainly against the spirit
of the spec, if not the letter.

Add and update the _NET_CLIENT_LIST property on the root window to
better comply with ewmh standards.
Information on this property can be found here:
http://standards.freedesktop.org/wm-spec/latest/ar01s03.html
> These arrays contain all X Windows managed by the Window Manager.
> _NET_CLIENT_LIST has initial mapping order, starting with the oldest window.

According to 4.1.7 of the iccm spec
http://tronche.com/gui/x/icccm/sec-4.html#s-4.1.7
> Windows with the atom WM_TAKE_FOCUS in their WM_PROTOCOLS property may
> receive a ClientMessage event from the window manager (as described in
> section 4.2.8) with WM_TAKE_FOCUS in its data[0] field and a valid
> timestamp (i.e. not CurrentTime ) in its data[1] field.
Adds the timestamp parameter to send_take_focus to avoid the dangerous
use of a global variable.
This patch fixes ticket #1168 to extend the window IPC event mechanism
to send IPC events for window focus and title changes. The newly added
window events use the same format as the already established "new"
event.
Specifically this patch:
* Moves the ipc_send_window_event() function from src/manage.c into
src/ipc.c and adds an argument for the change property of the event
* Updates src/manage.c to use the new function signature. To ensure
that the "new" event does not send the same event data as the
"focus" event, setting focus now happens after the "new" event
has been sent
* Adds IPC focus event notification to src/x.c. To workaround a problem
during window close when accessing the window name, a function has been
added to query whether a window is actually attached to its parent. To
avoid obsolete focus notification, a new field has been added to keep
track of the focus without any interference by the click handling
* Adds IPC title event notification to src/handlers.c. To avoid
obsolete title notification, a function has been added to determine
whether a window title has actually changed
* Updates the IPC documentation to include the new events
* Updates testcases/t/205-ipc-windows.t to include the "focus" event
in order to ensure the correct event sequence
* Adds two new unit tests, b/testcases/t/219-ipc-window-focus.t and
b/testcases/t/220-ipc-window-title.t to ensure proper "focus" and
"title" events
The pixmap of a borderless leaf container will not be used except
for the titlebar in a stack or tabs.
Make sure these containers do not (really) have a pixmap because it can
only get in the way.

When `focus_follows_mouse` configuration option is disabled, do not warp
the pointer when focus changes outputs after rendering.
Rationale: this option is meant to be disabled by users who have a setup
where the mouse is usually in the way. These users tend to move the
mouse to a corner or use a utility to hide the pointer when it is not
active. When this user switches focus between outputs, the mouse is
placed in the center of the screen.
This is clearly against the spirit of disabling `focus_follows_mouse`.
Disabling this option now implies disabling "mouse follows focus".
state->initial is set to false before calling x_push_node() since we
began pushing the window stack before pushing changes. Therefore, the
condition could never be true.
This reverts commit 0659a0d98c.
It was a fix for dzen2 setups, but broke several other use cases.
Because dzen2 is not really important since most people use i3bar
nowadays, let’s revert this.

Add shmlog command that takes <size>|toggle|on|off. Separate logbuffer
management into open_logbuffer() and close_logbuffer(). Make
t/187-commands-parser.t expect 'shmlog'. Add update_shmlog_atom() to
update the SHMLOG_PATH. Document the shmlog command in userguide.
In order to distinguish split layouts from tabbed/stacking layouts when
only one window is shown, do not draw the indicator border for tabbed or
stacking layouts.
Note that this is ineffective for dunst’s notifications because dunst
re-raises them as soon as they get obscured. It does work for dzen2
however, which was the original use-case.

The C compiler will handle (void) as "no arguments" and () as "variadic
function" (equivalent to (...)) which might lead to subtle errors, such
as the one which was fixed with commit 0ea64ae4.
You need to specify the --enable-32bit-visual flag when starting i3. This is
done because everything feels sluggish on my system when using a 32 bit visual
instead of a 24 bit visual. Fast > fancy.
