4f2f8bda11 Use GLSL 1.40 shaders as GLSL 300 es shaders for effects
Like for the scene shaders. Makes the effects work again when using
GLES 3.

60c42b7a34 s/KLocale/KLocalizedString/g
Many headers included KLocale to use i18n and co. But those methods are
defined in KLocalizedString and not in KLocale.

With KF5 klocale.h does no longer include KLocalizedString causing lots
of compile errors.

c2a4f81927 Introduce a helper class to automatically push/pop Shaders
The ShaderBinder class can be used for the case that a block of code
should be executed with a given Shader being bound. This is useful for
all the cases where there is a if-block for OpenGL2 execution with a
Shader being pushed in the first line to the ShaderManager and popped in
the last line of the block. With the helper this can be simplified to:

ShaderBinder binder(myCustomShader);

or

ShaderBinder binder(ShaderManager::GenericShader);

The ctor of ShaderBinder pushes the given Shader to the stack and once
the helper goes out of scope it will be popped again from the stack.

In addition the helper can take care of OpenGL 1 compositing, that is it
just does nothing. So it can also be used where there is a shared OpenGL1
and OpenGL2 code path where the Shader should only be pushed in OpenGL2.
This basically removes all the checks for the compositing type before
pushing/popping a Shader to the stack.

6d2dfe06e7 Introduce dedicated OpenGL1 and OpenGL2 compositing types
The CompositingType enum turns into flags and two new values are
introduced: OpenGL1Compositing and OpenGL2Compositing.

Those new values are or-ed to OpenGLCompositing so that a simple check
for the flag OpenGLCompositing works in case of one of those two new
values. To make the generic check for OpenGL compositing easier a method
in EffectsHandler is introduced to just check for this.

The scenes now return either OpenGL1Compositing or OpenGL2Compositing
depending on which Scene implementation. None returns OpenGLCompositing.

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.

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.
