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

This way we can get rid of the texture matrix transformations when rendering a standard texture - no matter if it's inverted or not.

This is a workaround to the problem that some drivers do not return a complete FBO, but support the extension. Which caused the blur effect to get loaded without working and in consequence Plasma to use the blur-optimized and very translucent backgrounds.

GL_BGRA is the native format, and should be faster since it doesn't
require any internal swizzling.

(Premultiplied text painting on a non-premultiplied QImage). Fixed text
color of frameless and unstyled frames when using a Plasma theme that
has a non-white primary text color. Updated
GLTexture::convertToGLFormat() to use the latest version from Qt.

geometry actually stays the same. Avoids large number of rebinds (with no
strict binding) with the launch feedback icon.

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

means any GPL). Decoration clients will come later.

array when rendering.
- Rearrange some renderGLGeometry() parameters.
- Don't use opengl arrays and glDrawArrays() when rendering a small number of vertices since in this
case overhead of enabling/disabling the array is too big. Use immediate mode instead in such case.
