Effects can specify their minimum requirements in their
desktop file:
* OpenGL
* OpenGL 2 (GLSL required)
* Shaders (either ARB or OpenGL 2)
The configuration module uses this information in combination
with which backend KWin is currently using. So if e.g. OpenGL
is used and an effect requires OpenGL 2 a detailed error
message can be showed that OpenGL 2 is required.

A CMake variable is used to specify the name of the binary.
By default this is "kwin" but building for PA changes the
name to "kwinactive". The variable adjusts all names, e.g.
kwinnvidiahack becomes kwinactivenvidiahack.
The remaining usage of kwinrc in core and libs is replaced
by a cmakedefine for the configuration name and all data
installations are moved to the defined name. Dynamic loading
for scripts & co is adjusted for loading based on defined name.
This change allows the side-by-side installation of both kwin
for desktop and kwin for Plasma Desktop without the known
issues like conflicts in config files or missing build options
if kwin desktop is used for Plasma Active.
Likewise the KCMs are not adjusted as they are not intended to
be used for kwinactive.

Additional TabBox Mode which allows to switch between all open
windows of the current selected application. By default Alt+tilde
is used which is on qwerty just one key above tab. For non-qwerty
layouts the shortcut is unfortunately not convenient.

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.

Creating an EffectFrame requires I/O which takes on my system
during testing between 10 and 40 msec. Also it needs a little
bit of memory.
This changes moves out the creation of EffectFrames at Effect
load till the Effect actually needs the EffectFrame. E.g. if a
user does not filter in PresentWindows there is no need to ever
create it.
BoxSwitch effect is ignored as it should be dropped for 4.9.

Cube effect loads 0 to 2 textures which has been
performed during configuration. This change delays
loading the textures till cube is activated for the
first time and the loading from file is moved into
a thread.
This means that for a very short time the texture
is not yet visible, but this is not a problem as
the cube animates from fully opaque starting state.
So during the loading the texture would not be
visible anyway.

This makes kwin in OpenGL2 mode more coherent with kwin_gles.
Despite some fullscreen effects they should now make the same
(pure) OpenGL calls.

Some old restructuring caused -DKWIN_HAVE_OPENGLES to no longer be
passed to the compiler, causing OpenGL-specific code to be built
while the libraries to link it were not available.

For the normal TabBox the TabBoxClient's icon method is
adjusted to use the "user-desktop" icon instead of the
window icon.
For the effects a method to set the caption is extended
to also set the icon on the caption frame.

FlipSwitch can be navigated with up and down keys as well
as left/right and CoverSwitch only with left and right

Our first effect written in JavaScript to replace an existing C++
effect. Fade effect has been chosen as it has shown to be problematic
in the past and would have needed a migration to AnimationEffect anyway.
This reduces the repaints in cases where several blur regions are
stacked on top of each other (e.g. oxygen-transparent) and the topmost
layer needs to be updated (e.g. a blurry window is moved).
