ae95ab0c43 Adding color to VBO. 
A color can be specified to render the geometry of the VBO.
For legacy painting glColor is used, for shader a uniform is set.
In order to allow rendering without texcoords, it is possible to pass
a null pointer as texcoords.
Shader added to scene which just renders a colored geometry without texturing.

a2e214d326 Enable PaintClipper on core VBO again. 
Need to disable clearing screen on EGL for that.
With Mesa swapping buffer is sufficient, though a better solution will be required for other drivers

ea12f95b27 Support setting y_inverted for Texture. 
At least needed for the pixmaps loaded by EGL.
Should be save on GLX as well, if not it needs fixing

b13f3f5f11 In ES it's GL_FRAMEBUFFER instead of GL_FRAMEBUFFER_EXT

56ce39def8 Core profile compatible basic scene rendering. 
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.

92bea91686 - moved rendering of antialiased corners from Oxygen::ShadowCache to Oxygen::Client. 
- simplified caching of ShadowCache accordingly. Notably, it should make it easier to pass the shadows to kwin.
- removed unnecessary QPainter::save()/restore() calls
- set painter AntiAliasing render hint earlier in Client::paintEvent
- modified drawing of drop target rect accordingly.
- oh. And fixed krazy warnings.
