Adds a shader to render an untransformed scene. renderGLGeometry is not used any more and replaced by generated triangles stored in a GLVertexBuffer.
The GLVertexBuffer has a new attribute to decide whether a core profile compatible rendering has to be performed.
Currently windows and EffectFrames can make use of the new shader.
The shader contains a debug mode which colours all rendered fragments in green. It is currently enabled in scene_opengl.
Rendering transformed geometries (without shader) is currently broken.
differecens to patch atteched to 258971:
- removed debug statements
- fixed indention...
- NON vsync strategy does not rely on the estimation, but on the time passed since the last repaint trigger, allowing a precise framerate

this should improve v'syncing, maybe v'synced "smoothness"

The GLX implementation in the X server appears to have a hardcoded limit
to how many pixmaps can be bound to textures simultaneously when using
indirect rendering, which we can end up exceeding with the changes
introduced in r1182198.

This worksaround a problem with the nouveau driver causing
the text frames to be incorrectly rendered. We need to keep
the QPixmap around as long as we have a texture created from
that texture.
This applies for the text and the unstyled effect frame. For
the frames generated from Plasma's FrameSvgs it is not required.

that it's supported.

We don't need to do this every time we bind the texture to a GL context,
even with strict binding.

For Software Rasterizer we never ever want to have OpenGL compositing.
No matter how many config options the user sets it has to be disabled.
Though falling back to XRender makes sense in the case of software
rasterization.

This allows an effect to fade between old and new text/icon. As an example it's added to CoverSwitch.
Currently only supported in OpenGL. XRender might be added, but I'm missing an idea for an effect to add it.
Most effects using EffectFrame require OpenGL anyway.

I missed this line in my previous change to disable the fallback which made the fallback happen nevertheless.

So it is more consistent (in KDE newspeak "elegant") with other selections and as a plus we get rid of all the custom rendering code in boxswitch.

Some effects (boxswitch and flipswitch) still need to be changed to not set the icon in each frame.

Rendering of the EffectFrame is moved into the scene as Scene::EffectFrame with a concrete implementation in SceneXrender and SceneOpenGL.
A factory method for an EffectFrame is added to the EffectsHandler, which is used by the effects.
Next step: pass the EffectFrame through all effects, so that effects can transform, blur, invert whatever it.

With Intel drivers currently the self check at KWin startup fails (no idea why) and KWin falls back to XRender. This is probably an explanation for all the complaints about slow kwin in 4.5 and the missing effects. So let's fail and make it possible to restart compositing via systemsettings and alt+shift+f12.
Nevertheless it would be nice to fix the the failing selfcheck...

at the same time (in other words, only when activating compositing using the kcm).
Currently selfcheck causes bad flicker (due to X mapping the overlay window
for too long?) which looks bad during KDE startup. With this patch, KDE startup
is without any flicker.

(i.e. currently it allows to enable compositing even if self-check fails).
Not recommended of course, and it's be still nice to get self-check work
reliably.

second test fails for some reason with BadAlloc in glXCreatePixmap().
Maybe nvidia bug, but could be also some hidden KWin bug (according
to GLX docs, glXCreatePixmap() can give BadAlloc only when it can't
allocate, which is nonsense here, but glXCreateWindow() says that
BadAlloc may mean calling it twice on the same window, so maybe
here it's twice with the same pixmap - I don't see where the bug
could be though).

really works by simply trying to do it and test the result - create a small
testing window with known content, do the same with it like with normal
windows, grab the screen contents, compare with the original, doesn't match? -> fail.
It still would be nice to have something similar for performance.

Therefore zScale, zTranslate and new RotationData are added to ScreenPaintData and WindowPaintData. So it is possible to define zTranslation and rotations without using OpenGL directly. The change only affects OpenGL compositing. XRender is not changed.

Also slightly redo the #define's for effects, now it's:
- #ifdef KWIN_HAVE_COMPOSITING to check whether there's any compositing support at all
- #ifdef KWIN_HAVE_OPENGL_COMPOSITING to check for OpenGL-based compositing
- #ifdef KWIN_HAVE_XRENDER_COMPOSITING the same for XRender
