19f6b9667b Remove ShaderEffect from KWinEffects Library. 
The class is not used by any effect any more and the
design of the ShaderEffect makes it hardly usable.
For most effects just rendering the windows with the Shader
attached to it makes more sense than rendering the complete
screen into a FBO and apply the shader on the off-screen texture.

61615ea7ff Need to copy QPixmap to QImage in GLES. 
The Image extension seems to need the pixmap around and that's something
we cannot guarantee in the generic case.

d683ce560c Adding new uniform to enforce that alpha becomes 1.0 
When rendering opaque (RGB-only) windows the alpha ends up to be 0
with blending disabled. This breaks subsequent rendering steps which
require blenden (e.g. Lanczos). Therefore a uniform is used to ensure
that the alpha channel is set to 1.

e49345872c Add high-level functions for <push|pop|mult>Matrix. 
All methods are no-ops for GLES which allows to use them from
effects without checks for GLES.

990001c5d7 Drop GLVertexBuffer::useShader. 
The vertex buffer implementation uses the shader manager to decide
whether core painting should be used or not. Shader manager is only
used by shaders using vertex attributes instead of gl_Vertex etc.

a4e4752109 Combine built-in vertex with custom fragment shader 
ShaderManager supports a new concept to load just a fragment shader from file
and use a built-in shader for the vertex shader. This allows an effect to use
a custom fragment shader.

3c6e7309f2 New ShaderManager 
The ShaderManager provides the built-in shaders for scene and effects.
Scene and effects can simply push one of those built-in shaders or a
custom one on a stack ensuring that the previously bound shader will be
rebound when the shader is poped again.

The class will be extended to not only have built-in shaders but also to
load custom shaders and being the only way to bind a shader at all.

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.

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
