Alexander Volkov 2047fe9253 xcb: Process _NET_WORKAREA and screen geometry changes separately
This commit allows to avoid superfluous calls to the X server.
We don't request _NET_WORKAREA values when the screen geometry changes,
and we avoid RandR calls on each _NET_WORKAREA change.
Besides, update the available geometry of all screens with the
same root window, rather than only that one which corresponds
to Qt::Desktop window.

Paul Olav Tvete 4e1b09fa8f Keep screen geometries from overlapping
The simple mapping of dividing each position by the
devicePixelRatio does not work when screens have different
DPR. If the low-DPR screen above or to the left of the high-DPR
screen, the geometries will overlap in the Qt coordinate system.

This change introduces a new mapping where the origin of each screen
does not move. This mapping is not perfect: it will have gaps between
contiguous screens. However, it will keep non-overlapping screens
non-overlapping in the Qt coordinate system.

Since there is no longer a simple linear coordinate transform, we
have to add screen-dependent mapping functions, and distinguish between
local and non-local coordinates. A side benefit is that the code is
now easier to read, since we remove most manual coordinate transformation.

We also have to cache the screen of each window: since we send resize events
before screen change events, we cannot rely on QPlatformWindow::screen()
(which is set from the screen change event).

Daniel Vrátil 3b30a8215e Improve handling of XRandR events in XCB backend
Querying X server for data can be very expensive, especially when there
are multiple processes querying it at the same time (which is exactly what
happens when screen configuration changes and all Qt applications receive
XRandR change notifications). This patch is aiming to reduce the number of
queries to X server as much as possible by making use of detailed information
available in the RRCrtcChangeNotify and RROutputChangeNotify events.

Firstly, the backend now does not rebuild all QXcbScreens on any change (which
involved the very expensive xcb_randr_get_screen_resources() call), but only
builds the full set of QXcbScreens once in initializeScreens(), and then just
incrementally updates it.

Secondly, it avoids querying X server for all screens geometry as much as
possible, and only does so when CRTC/Output change notification for a particular
screen is delivered.

As a result, handling of all XRandR events on screen change is reduced from tens
of seconds to less then a seconds and applications are better responsive after
that, because we don't block the event loop for long. The X server is also more
responsive after the screen change, since we are not overloading it with requests.

Leo Franchi 0eefa785a0 Support transparency in qt5 system tray icons, regardless of tray visual
This ports the Qt4 method of supporting the system tray
window visual that has an alpha channel as well as ones
that do not. We detect whether or not we have a 32-bit
format and either use a Qt::transparent background, or
call xcb_clear_region before painting the icon.

[ChangeLog][Linux/XCB] Fix transparency of tray icons in cases where
there is no alpha channel or system tray visual.

Martin Gräßlin 075c36e39b Do not overwrite existing event mask of root window
QXcbScreen installs its own event mask on the screen's root window.
This overwrites any existing event mask already set and by that
breaks applications when a new screen is added.

By first fetching the existing event mask and adding it to the newly
installed event mask, Qt does no longer break applications also
installing an event mask on the root window.

Martin Klapetek 2ae50d9123 Update QScreen::availableGeometry() on _NET_WORKAREA atom changes
When the window manager sets new workarea using the _NET_WORKAREA xcb
atom, QScreen::availableGeometry() does not react to that and returns an
invalid available geometry. This patch reacts to that change and updates
the QScreen property properly on xcb platform.

Thiago Macieira 5ee3d1e456 XCB: Don't recalculate the DPI if we have a forced DPI setting
logicalDpi() already has the logic to check m_forcedDpi, so let's reuse
it. I hope it's not a problem that we send a signal that it changed when
nothing changed.

[ChangeLog][Platform Specific Changes][X11 / XCB]Fixed a bug that caused
Qt applications to think the screen DPI had changed when it had not,

Shawn Rutledge 51c28cad67 xcb: every window should have a title in debug mode
Qt creates various invisible windows for internal purposes.
Giving them all titles makes the output of tools like
xprop and xwininfo more readable, which makes solving certain bugs
(like transient-window bugs) easier.

Friedemann Kleint d8090022f6 Move the X11 system tray code from widgets into XCB-plugin.
- Add system tray tracker class to XCB plugin and
  provide functionality via invokable slots
  of the native interface.
- Remove XLib-dependency of widgets/utils.
- Reintroduce tracking of tray window destruction
  and recreation, which was removed in the XLib-code
  when porting it from Qt 4 to Qt 5.

This paves the way for implementing the tray icon
completely in terms of QPlatformSystemTrayIcon at some point
later.

Jørgen Lind 0f31a5d91f Introduce QXcbXSettings
This allows you to easily retrieve properties in the XSETTINGS
specification. It is also possible to add listeners to get notified when
a specific property changes.

XSETTINGS is lazy initialized, so it will not be instansiated before
someone uses it. For now the intended use is a fallback for finding
cursor theme
