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.

764338e042 TaskbarThumbnails should say that it needs transformed windows. 
Fixes a nice transformation issue when using thumbnails after cube effect.

78c4c7a86e Lanczos filter available in GLES. 
It uses a default vertex shader, so the existing shader can be dropped.

2e0385101a Less ifdef in paintWindow. CleanerCode++ 
Using the QMatrix4x4 allows to make everything runtime dependent
and not a compile time switch.

8c4db8f734 Say goodbye to Display Lists in cube. 
Rotation is now only handled by the QMatrix4x4 m_rotationMatrix,
so no more need for display lists. Resulting in a cleaner code without
differences between OpenGL 1.x and 2.x/GLES.

6b88cdf36a Cube uses new high-level push/pop/multiply for caps. 
For OpenGL 1.x cube caps are now rendered using the capMatrix
instead of using glTranslate/glRotate et al. One source base to
rule all GL versions.

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.

75a1ee7aa8 CubeCaps back in GLES mode. 
This includes quite some refactoring. For the cube cap a VBO is used
instead of glLists and all the required transformations are moved into
paintCap() which makes paintScreen more clean.
Currently the mirroring of bottom texture is still missing and cylinder
and sphere caps are not yet ported to using VBO.
I wouldn't be surprised if it is broken for legacy GL atm.

ad070909a3 Reflection plane in Coverswitch and GLES 
CoverSwitch uses new concept of combining a custom fragment shader with the
built-in generic vertex shader. This shader is used to render the reflection
plane on top of the reflected windows.
The fragment shader uses two uniform colors for front and back and interpolates
between them based on the texcoords (which are not used for texture lookup).
The reflection plane vertices could be buffered.

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.

Not working:
* Cube Inside effects
* Reflection plane (needs to be done in a shader)
* cube caps
* sphere/cylinder
* filled in areas in multi desktop
