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.
Adding a new AbilityUsesBlurBehind which can be set by decorations with
alpha channel to request that the background can be blurred. This improves
the situation for our completely opaque default Oxygen decoration.
This change is a behavior change in comparison to 4.5! Translucent decorations do
not get blurred by default any more.

This provides a significant performance improvement especially for Present Windows.
Whenever a lanczos resampling is done the resulted texture is cached, till the
window is damaged or a texture of different size is required. This means that
for a taskbar thumbnail the resampling only occurs once unless the window is damaged
and for present windows it only occurs when the windows are resized and then only
after the windows have already been moved. Highlighting windows does not cause
a resampling any more.

When moving a window to the upper or lower quarter of a screen edge the window will be quick tiled to the responsible quarter of the screen.
Moving the window to the middle half of the screen will do the normal quicktiling to half of screen, quick maximization at top screen is unchanged.
Thanks to Arthur Arlt for his first code contribution to KDE.

Revert rev 1137490: it caused compositing not working with legacy NVIDIA drivers and might be responsible for freezes when changing config.
It can be reverted as there is already a better fix for buggy drivers present in 4.5.1.
Did I mention that I love drivers?

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.

It is not always required to do a full repaint in each frame. E.g. in sliding popups the repaint areas are known and tracked.
This change reduces the painting overhead to just the window area.
Nevertheless I consider this change as experimental and will revert the commit in case it introduces rendering glitches.
Other effects which are good candidates for this flag is wobbly windows, magic lamp, minimize or in general all effects which transform just one window.

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.

This gives us one API for both legacy and modern painting.
All glRenderGeometry* calls are deprecated as they use quads and
legacy painting.
