a79eacaed7 Properly detect effects which need OpenGL 2 
Effects that need GLSL require that OpenGL 2 is active.
It does not matter whether the GPU would support it if
OpenGL 2 is not used.

Cherry-picked from db42152

ef9aeafe0d kwin: Optimizing Blur Part II 
This patch adds an optional texture cache to the blur effect such that damaged windows in
front of the blurred region dont trigger a repaint of the whole blurred region which pretty
often results in a avalanche repaint of nearly the whole screen.

fe4329a252 Only call active effects in the effect chain 
Each effect is able to declare itself as currently being active,
that is transforming windows or painting or screen or doing anything
during the current rendered frame.

This change eliminates the hottest path inside KWin identified by
callgrind.

e5e5c4a020 Move push/popRenderTarget to kwingluitls 
(De)Activating a FBO is OpenGL specific and does not belong into EffectsHandler.

0827c2903b Use GLPlatform to decide whether shaders are supported 
Dropping the static methods from GLShader and use supports()
where it was used before.

6cd6883d8c Remove too strong error checks. 
That should never have been committed, it was just for finding an error.

863726a085 LookingGlass ported to GLES. 
LookingGlass does not inherit ShaderEffect any more and uses just a
fragment shader. It still renders to a FBO, this could probably be
improved.

846496d2c1 Cleaned up the effects/ directory by moving each individual effect into 
its own directory, cleaned up the effect config macros and renamed
"MakeTransparent" to "Translucency" so that it matches its visible name.
