d38bce776f Add support for skip close animation to OnScreenMessage
Summary:
This change adds support for marking the OnScreenMessage as it should
skip close animation. The screenshot effect is adjusted to use the
on screen message instead of the custom effect frame.

Test Plan: Message window is not captured when taking screenshot

f9f7b84cb4 Add interactive position selection to screenshot screen under cursor
Summary:
A second interactive selection mode gets added to select a position on
the screen. This is handled by the same input event filter as for the
window selection. Just that instead of returning a window, it returns a
QPoint.

This allows to pick a point on the screen which we need to screenshot
the screen under the mouse cursor and in future for color picking.

The screenshot effect provides two new dbus methods to (interactively)
select a screen or fullscreen. This allows spectacle to screenshot the
(full) screen with still having the user in control.

fbab204968 [effects] Add a screenshot dbus method which takes a file descriptor
Summary:
The idea behind this mode is to support applications like spectacle
(see T4458). The calling application passes a file descriptor (created
through e.g. a pipe) and the screenshot effect writes the captured image
into that fd.

The advantage over the existing variant which writes to a file in the
/tmp directory is that this is peer-to-peer between the requesting
application and KWin. No other application can get to that image.

The change also includes setting SIGPIPE to ignore. It showed that when
the reading side already cancelled the read prior to KWin writing out
the image we get a SIGPIPE which results in application termination,
which is not what we want in case of a Wayland compositor. The sigpipe
can be ignored as Qt (and libpng) handles that error just fine at
runtime.

cfdc1acbd3 [effects] Show info message in interactive window screenshot mode
Summary:
While taking an interactive screenshot we should inform the user about
what's going on, how to take the screenshot and how to cancel it.

For this the effect creates an EffectFrame with the required
information.

27376e39ef [effects] Add interactive window selection mode to ScreenshotEffect
Summary:
EffectsHandler gains a new method to startInteractiveWindowSelection
which just delegates to the one in Platform. That way a window can be
selected and returned to an Effect.

The screenshot effect makes use of this new functionality and provides
an interactive window screenshot mode which saves to a temporary file.
Note that this is not yet the variant intended for use in spectacle.

8c163f2b93 [effects] Support capture cursor image in Screenshot effect
Summary:
The screenshot methods to blit the screen so far did not capture the
cursor image. But sometimes it is useful to also capture the cursor
image.

This change extends the exported methods to take an optional bool
argument whether to capture the screen. The default is not changed and
still not captures the cursor.

eadfcb3d4f [effects] Make screenshot effect work with multiple output rendering
Summary:
Adjusts the screenshot effect to mutliple output rendering. In that case
the blit from framebuffer can only get one output. Thus the effect needs
to blit every output and combine the rendering result.

e9b25f176a [effects] Delay taking screenshot into next rendering cycle
Summary:
For windows the screenshot effect already delayed the rendering into the
next cycle. But for the fullscreen variants which save to a file the
Screenshot effect did try to take the shot directly.

This can be problematic as e.g. the OpenGL context might not be bound at
all. Also this makes it impossible to screenshot multiple screens
together in the Wayland case.

This change delays the DBus replies, schedules the geometry and takes
the screenshot in the next rendering pass. It does not fix the
multiscreen wayland problem yet.

3bbc9436db [kwin] Add a virtual Effect::requestedEffectChainPosition
This method replaces the X-KDE-ORDERING property in the Effect's desktop
files. This change is a preparation step for integrating the new Effect
Loader which doesn't read the ordering information. Thus it needs to be
provided by the Effect itself so that the EffectsHandler can properly
insert it into the chain.

Also for the built-in Effects on the long run it doesn't make much sense
to install the desktop files. And binary plugin effects will migrate to
json metadata which also doesn't have the KService::Ptr. Thus overall it
simplifies to read this information directly from the Effect.

b8c6831a1f Port Screenshot effect to XCB
This includes:
* getting cursor image through xcb_xfixes
* using xcb_image_get for reading screen content in xrender case
* using xcb_put_image to upload the generated screenshot into shared xpix

Overall this means that QPixmap as an X Pixmap wrapper is no longer used.
The conversion from xcb_image_t to QImage still needs some code for not
matching byte order. I'm a little bit unsure about adding the code as I
would not be able to test it.

b7f06b8708 Use window size for offscreen texture size in screenshot effect
Effect used the display size which caused windows being larger than
either width or height not to be captured correctly.

Now it uses the window size for the offscreen texture which also requires
to adjust the modelviewprojection matrix.

As an unrelated change the pointer to GLRenderTarget and GLTexture are
changed to a QScopedPointer and some variables which got moved around
are consted.

fe4329a252 Only call active effects in the effect chain
Each effect is able to declare itself as currently being active,
that is transforming windows or painting or screen or doing anything
during the current rendered frame.

This change eliminates the hottest path inside KWin identified by
callgrind.
