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.

0b85768ec5 EffectsHandler emits windowClosed signal 
Client and Unmanaged use a signal to notify that they are about to be closed.
The EffectsHandlerImpl is connected to those signals and emits the appropriate
windowClosed signal to which the effects are connected.

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

54c0a913b9 Fixing broken Invert effect build. 
Forgot to remove the header file for shadereffect, though
it was not used anymore in the effect.

b7ee35bba1 Invert effect ported to GLES. 
It uses a generic vertex shader and because of that it needs to
mark all windows which are inverted as transformed.
There is currently a conflict with Lanczos (or thumbnails) and with
the desktop in cube effect.

89c0ea0c8d Pass EffectFrame through all effects, so that they can do something with the frame. 
E.g. set a shader to invert it.

612972eea0 Boxswitch uses paintWindow instead of drawWindow to paint the thumbnail and invert uses drawWindow instead of paintWindow to set the shader. 
That way the thumbnail is passed through the whole rendering pass and has the same invert state as the window.

d7665af4f0 Texture width and height is stored in GLShader and the uniform value is set during prepareShaderRenderStates in scene_opengl. So the effects do not have to set the uniform manually. This is useful as other effects can still set this uniform if something different is rendered with a different texture width/height (e.g. shadows or thumbnails). When the window is finally rendered the original value set by the effect is definatelly used. 
First effect to use this new way to set texture width and height is invert effect.

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.
