On laptops and similar devices, RandR sometimes returns zero active
screens, for example when closing a laptop's lid before it suspends.
Don't restart in that case because the new polybar instance will see
zero screens and quit. Instead, just ignore those kind of events.
Without override-redirect, i3 will not allow you to have a
non-full-width bar. But polybar simply ignores that request and
continues to render the user-requested width instead of the width i3 has
configured the window to be.
With the 3.7 release, we started setting the window's backing pixmap to
the rendering pixmap. In the case above, the pixmap would only be
allocted for the smaller width and when i3 maps the window, it repeats
the backing pixmap to fill the entire window.
At the point where i3 maps the window, the pixmap contains an initial
render of the bar without module content and that render is then
duplicated.
Reverting back to the old approach of simply copying over the pixmap
after each render does not have that problem and the remainder of the
bar is black (or fully transparent with a compositor).
Ideally, polybar would respect the width i3 configures for it, but that
would break many existing setups that rely on non-full-width bars in i3
Fixes#3060
Modules that don't produce any output are hidden by the controller
(don't have margins or separators).
The tray module should also do that for `format = <tray>` when there are
no icons.
This required the visibility handling to be tied to the module
visibility instead of being handled by the renderer.
Otherwise, the renderer would hide the tray (because the %{Pt} tag was
never sent) and the tray would not unhide when new icons appeared; it
can't differentiate between hidden because empty and hidden because the
module is hidden by the user (the latter is the reason the renderer does
hiding at all).
Fixes#3036
The ewmh strategy has to be dropped because the
`_NET_SUPPORTING_WM_CHECK` window may (at least in bspwm) appear
anywhere in the window stack.
To fix the overlapping monitors issue in #2873, we simply restack
against the topmost of these root windows.
Fixes#2972Fixes#2873 (again)
Positions the bar window above the _NET_SUPPORTING_WM_CHECK window
The generic restacking strategy now first tries the ewmh strategy, the
the bottom strategy.

* Return shared_ptr from eventloop
* Add -Wdeprecated-copy-dtor warning
Produces a warning if classes don't have explicit copy operations if
they have a user-defined constructor.
This helps us stick to the rule of 5 (kinda, no warnings for missing
move operators).
* Clean up eventloop
* Fix compiler warnings
* Fix fs_event_handle_t name
* Use m_connection.poll_for_event
* fix: Handle X events before polling for IO
Polling the XCB file descriptor for X events doesn't detect events that
are already in XCB's event queue but not yet handled.
If this happens, the eventloop polls for IO and the queued events wait
until another event arrives, causing some desyncs in the bar.
This can easily happen if something (e.g. a click event) triggers some
xcb calls, which as a consequence buffer some incoming events.
We "fix" this by adding a libuv prepare handle (which runs right before
polling for IO) that processes pending X events.
The background_manager used the root window depth for creating its
pixmaps, but when the root pixmap has a different depth, this causes the
copy_area_checked call to fail and crash the bar.
We now load the root pixmap before finding the visual and creating the
slice pixmaps.
Fixes#2798
Each tray client is directly reparented to the bar window. This saves us
the hassle of having to configure a basically useless tray window and
keeping its background pixmap in sync.
The only disadvantages are having to (un)map each client window
individually and calculating its position relative to the bar window
(which changes all the time) instead of relative to the tray window
(which only changes when clients are added/removed).
When a module is clicked, only wait for the double click interval if a
double click action is associated with that module. Otherwise trigger
the click right away.
Fixes: #2663
