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.

6d2dfe06e7 Introduce dedicated OpenGL1 and OpenGL2 compositing types
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.

05198bc2b7 Ifdef XRender related code in Screenshot effect
For PA KWin is compiled without XRender but with Screenshot effect
causing the compile to fail.

ef9aeafe0d kwin: Optimizing Blur Part II
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.

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.

78dd6e6859 Fix rendering glitch in screenshot effect with Raster
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.

234ec644d2 KWin supports graphicssystem Raster
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.

379e1a268b Screenshot effect provides hooks for KSnapshot.
This adds a DBus slot to capture a window and the pixmap handle
is passed back via a DBus signal.
Previous code using a shortcut and saving to filesystem is dropped
completely in favor for ksnapshot.

49fea7de58 New screenshot effect.
Saves an image of the active window into the home directory when triggered.
It uses an OpenGL FBO and by that can include the alpha channel and the decoration shadows.
