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.

Instead of having a pointer to a QPixmap the offscreen target holds an
xcb_render_picture_t. To make this possible in SceneWindow the tempPixmap
is changed from a QPixmap* to a XRenderPicture*. QPixmap was only used
for convenience.
ScreenShot Effect as only user of the offscreen target is adjusted but
as it needs a QImage, still uses a QPixmap wrapper.
EffectsHandlerImpl starts to monitor DBus for the screen being locked and
provides this information to the Effect system by allowing them to ask
whether the screen is currently locked and by emitting a signal when the
screen gets locked/unlocked.
This information is needed to ensure that no private data is shown on the
screen. The following effects are adjusted:
* taskbar thumbnails
* thumbnail aside
* mouse mark
* screen shot

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.

The CompositingType enum turns into flags and two new values are
introduced: OpenGL1Compositing and OpenGL2Compositing.
Those new values are or-ed to OpenGLCompositing so that a simple check
for the flag OpenGLCompositing works in case of one of those two new
values. To make the generic check for OpenGL compositing easier a method
in EffectsHandler is introduced to just check for this.
The scenes now return either OpenGL1Compositing or OpenGL2Compositing
depending on which Scene implementation. None returns OpenGLCompositing.

This patch adds an optional texture cache to the blur effect such that damaged windows in
front of the blurred region dont trigger a repaint of the whole blurred region which pretty
often results in a avalanche repaint of nearly the whole screen.

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.

We have to set the bit depth of the XPixmap to 32 in order to get
an alpha channel and we have to render the grabbed image using
composition mode Source in order to just copy all pixels to the
destination pixmap.
BUG: 276719
FIXED-IN: 4.7.0
With raster a QPixmap is no longer a XPixmap which fails all code
which assumes that an QPixmap is an XPixmap. Depending on were in
the codebase we either convert such pixmaps to images (OpenGL) or
create a XPixmap and use QPixmap::fromX11Pixmap to get a "real"
pixmap.
It is possible that there are more code pathes were we would need
a XPixmap. Currently tested is basic functionality of no-compositing,
XRender compositing, OpenGl/GLX and OpenGL ES/EGL compositing.
For OpenGL compositing raster might result in performance improvements,
for XRender it is possible that there are regressions when using raster.
By default KWin uses whatever is the default of the system, so we just
no longer enforce native.
Of course it is a bad idea to use graphicssystem OpenGL. As that
is broken anyways in Qt, we do not check for it.
Many thanks to Philipp Knechtges for bringing up the issue, convincing
me that we need it and providing most of the patch.
