OpenGL (if present) and once with OpenGL ES (if present). To better support this \
kwinglutils becomes an own library and is splitted out of the kwineffects library. It \
is build once as kwinglutils and once as kwinglesutils.

The effects are built twice into a kwin4_effect_builtins and \
kwin4_effect_gles_builtin. And last but not least we build a kwin and a kwin_gles.

The last part I consider as a temporary solution till Arthur finished the part of \
making scene* completely independent from kwin core. When that is done I want to only \
compile the compositor twice and load it as a plugin depending on the result of an \
external test program (so that NVIDIA users cannot get trying to load the non working \
GLES).

The change to compile everything twice is for the following reasons:

1. Should make life easier for distributions to provide kwin_gles

2. To have the Wayland support only in kwin_gles (does not make sense in kwin+desktop \
GL)

3. To make testing easier by just starting kwin --replace and kwin_gles --replace

Current issues and things I want to do:

* kwineffects still links libGL as it provides a check whether GLX is available. I \
think this one can be dropped (should only be used at one place in scene)

* Add another marco to ensure that kwin+gl cannot load GLES effects and vice versa

* Clean up the build files

* think about whether we need XRender when building the gles backend

@Alex: it would be nice if you could have a look at the changes and if they look \
fine.

@Plasma: Please have a look whether there is something useful for Plasma Active - the \
patches should (mostly) apply to 4.7</pre>  </td>
